About the MPI Library
|
||||
---------------------
|
||||
|
||||
The files 'mpi.h' and 'mpi.c' define a simple, arbitrary precision
|
||||
signed integer arithmetic package. The implementation is not the most
|
||||
efficient possible, but the code is small and should be fairly easily
|
||||
portable to just about any machine that supports an ANSI C compiler,
|
||||
as long as it is capable of at least 16-bit arithmetic (but also see
|
||||
below for more on this).
|
||||
|
||||
This library was written with an eye to cryptographic applications;
|
||||
thus, some care is taken to make sure that temporary values are not
|
||||
left lying around in memory when they are no longer in use. This adds
|
||||
some overhead for zeroing buffers before they are released back into
|
||||
the free pool; however, it gives you the assurance that there is only
|
||||
one copy of your important values residing in your process's address
|
||||
space at a time. Obviously, it is difficult to guarantee anything, in
|
||||
a pre-emptive multitasking environment, but this at least helps you
|
||||
keep a lid on the more obvious ways your data can get spread around in
|
||||
memory.
|
||||
|
||||
|
||||
Using the Library
|
||||
-----------------
|
||||
|
||||
To use the MPI library in your program, you must include the header:
|
||||
|
||||
#include "mpi.h"
|
||||
|
||||
This header provides all the type and function declarations you'll
|
||||
need to use the library. Almost all the names defined by the library
|
||||
begin with the prefix 'mp_', so it should be easy to keep them from
|
||||
clashing with your program's namespace (he says, glibly, knowing full
|
||||
well there are always pathological cases).
|
||||
|
||||
There are a few things you may want to configure about the library.
|
||||
By default, the MPI library uses an unsigned short for its digit type,
|
||||
and an unsigned int for its word type. The word type must be big
|
||||
enough to contain at least two digits, for the primitive arithmetic to
|
||||
work out. On my machine, a short is 2 bytes and an int is 4 bytes --
|
||||
but if you have 64-bit ints, you might want to use a 4-byte digit and
|
||||
an 8-byte word. I have tested the library using 1-byte digits and
|
||||
2-byte words, as well. Whatever you choose to do, the things you need
|
||||
to change are:
|
||||
|
||||
(1) The type definitions for mp_digit and mp_word.
|
||||
|
||||
(2) The macro DIGIT_FMT which tells mp_print() how to display a
|
||||
single digit. This is just a printf() format string, so you
|
||||
can adjust it appropriately.
|
||||
|
||||
(3) The macros DIGIT_MAX and MP_WORD_MAX, which specify the
|
||||
largest value expressible in an mp_digit and an mp_word,
|
||||
respectively.
|
||||
|
||||
Both the mp_digit and mp_word should be UNSIGNED integer types. The
|
||||
code relies on having the full positive precision of the type used for
|
||||
digits and words.
|
||||
|
||||
The remaining type definitions should be left alone, for the most
|
||||
part. The code in the library does not make any significant
|
||||
assumptions about the sizes of things, but there is little if any
|
||||
reason to change the other parameters, so I would recommend you leave
|
||||
them as you found them.
|
||||
|
||||
The library comes with a Perl script, 'types.pl', which will scan your
|
||||
current Makefile settings, and attempt to find good definitions for
|
||||
these types. It relies on a Unix sort of build environment, so it
|
||||
probably won't work under MacOS or Windows, but it can be convenient
|
||||
if you're porting to a new flavour of Unix. Just run 'types.pl' at
|
||||
the command line, and it will spit out its results to the standard
|
||||
output.
|
||||
|
||||
|
||||
Conventions
|
||||
-----------
|
||||
|
||||
Most functions in the library return a value of type mp_err. This
|
||||
permits the library to communicate success or various kinds of failure
|
||||
to the calling program. The return values currently defined are:
|
||||
|
||||
MP_OKAY - okay, operation succeeded, all's well
|
||||
MP_YES - okay, the answer is yes (same as MP_OKAY)
|
||||
MP_NO - okay, but answer is no (not MP_OKAY)
|
||||
MP_MEM - operation ran out of memory
|
||||
MP_RANGE - input parameter was out of range
|
||||
MP_BADARG - an invalid input parameter was provided
|
||||
MP_UNDEF - no output value is defined for this input
|
||||
|
||||
The only function which currently uses MP_UNDEF is mp_invmod().
|
||||
Division by zero is undefined, but the division functions will return
|
||||
MP_RANGE for a zero divisor. MP_BADARG usually means you passed a
|
||||
bogus mp_int structure to the function. MP_YES and MP_NO are not used
|
||||
by the library itself; they're defined so you can use them in your own
|
||||
extensions.
|
||||
|
||||
If you need a readable interpretation of these error codes in your
|
||||
program, you may also use the mp_strerror() function. This function
|
||||
takes an mp_err as input, and returns a pointer to a human-readable
|
||||
string describing the meaning of the error. These strings are stored
|
||||
as constants within the library, so the caller should not attempt to
|
||||
modify or free the memory associated with these strings.
|
||||
|
||||
The library represents values in signed-magnitude format. Values
|
||||
strictly less than zero are negative, all others are considered
|
||||
positive (zero is positive by fiat). You can access the 'sign' member
|
||||
of the mp_int structure directly, but better is to use the mp_cmp_z()
|
||||
function, to find out which side of zero the value lies on.
|
||||
|
||||
Most arithmetic functions have a single-digit variant, as well as the
|
||||
full arbitrary-precision. An mp_digit is an unsigned value between 0
|
||||
and DIGIT_MAX inclusive. The radix is available as RADIX. The number
|
||||
of bits in a given digit is given as DIGIT_BIT.
|
||||
|
||||
Generally, input parameters are given before output parameters.
|
||||
Unless otherwise specified, any input parameter can be re-used as an
|
||||
output parameter, without confusing anything.
|
||||
|
||||
The basic numeric type defined by the library is an mp_int. Virtually
|
||||
all the functions in the library take a pointer to an mp_int as one of
|
||||
their parameters. An explanation of how to create and use these
|
||||
<HR>
|
||||
<A NAME="p23">
|
||||
<H3>Problem 23:</H3>
|
||||
|
||||
structures follows. And so, without further ado...
|
||||
|
||||
|
||||
Initialization and Cleanup
|
||||
--------------------------
|
||||
|
||||
The basic numeric type defined by the library is an 'mp_int'.
|
||||
However, it is not sufficient to simply declare a variable of type
|
||||
mp_int in your program. These variables also need to be initialized
|
||||
before they can be used, to allocate the internal storage they require
|
||||
for computation.
|
||||
|
||||
This is done using one of the following functions:
|
||||
|
||||
mp_init(mp_int *mp);
|
||||
mp_init_copy(mp_int *mp, mp_int *from);
|
||||
mp_init_size(mp_int *mp, mp_size p);
|
||||
|
||||
Each of these requires a pointer to a structure of type mp_int. The
|
||||
basic mp_init() simply initializes the mp_int to a default size, and
|
||||
sets its value to zero. If you would like to initialize a copy of an
|
||||
existing mp_int, use mp_init_copy(), where the 'from' parameter is the
|
||||
mp_int you'd like to make a copy of. The third function,
|
||||
mp_init_size(), permits you to specify how many digits of precision
|
||||
should be preallocated for your mp_int. This can help the library
|
||||
avoid unnecessary re-allocations later on.
|
||||
|
||||
The default precision used by mp_init() can be retrieved using:
|
||||
|
||||
precision = mp_get_prec();
|
||||
|
||||
This returns the number of digits that will be allocated. You can
|
||||
change this value by using:
|
||||
|
||||
mp_set_prec(unsigned int prec);
|
||||
|
||||
Any positive value is acceptable -- if you pass zero, the default
|
||||
precision will be re-set to the compiled-in library default (this is
|
||||
specified in the header file 'mpi-config.h', and typically defaults to
|
||||
8 or 16).
|
||||
|
||||
Just as you must allocate an mp_int before you can use it, you must
|
||||
clean up the structure when you are done with it. This is performed
|
||||
using the mp_clear() function. Remember that any mp_int that you
|
||||
create as a local variable in a function must be mp_clear()'d before
|
||||
that function exits, or else the memory allocated to that mp_int will
|
||||
be orphaned and unrecoverable.
|
||||
|
||||
To set an mp_int to a given value, the following functions are given:
|
||||
|
||||
mp_set(mp_int *mp, mp_digit d);
|
||||
mp_set_int(mp_int *mp, long z);
|
||||
|
||||
The mp_set() function sets the mp_int to a single digit value, while
|
||||
mp_set_int() sets the mp_int to a signed long integer value.
|
||||
|
||||
To set an mp_int to zero, use:
|
||||
|
||||
mp_zero(mp_int *mp);
|
||||
|
||||
|
||||
Copying and Moving
|
||||
------------------
|
||||
|
||||
If you have two initialized mp_int's, and you want to copy the value
|
||||
of one into the other, use:
|
||||
|
||||
mp_copy(from, to)
|
||||
|
||||
This takes care of clearing the old value of 'to', and copies the new
|
||||
value into it. If 'to' is not yet initialized, use mp_init_copy()
|
||||
instead (see above).
|
||||
|
||||
Note: The library tries, whenever possible, to avoid allocating
|
||||
---- new memory. Thus, mp_copy() tries first to satisfy the needs
|
||||
of the copy by re-using the memory already allocated to 'to'.
|
||||
Only if this proves insufficient will mp_copy() actually
|
||||
allocate new memory.
|
||||
|
||||
For this reason, if you know a priori that 'to' has enough
|
||||
available space to hold 'from', you don't need to check the
|
||||
return value of mp_copy() for memory failure. The USED()
|
||||
macro tells you how many digits are used by an mp_int, and
|
||||
the ALLOC() macro tells you how many are allocated.
|
||||
|
||||
If you have two initialized mp_int's, and you want to exchange their
|
||||
values, use:
|
||||
|
||||
mp_exch(a, b)
|
||||
|
||||
This is better than using mp_copy() with a temporary, since it will
|
||||
not (ever) touch the memory allocator -- it just swaps the exact
|
||||
contents of the two structures. The mp_exch() function cannot fail;
|
||||
if you pass it an invalid structure, it just ignores it, and does
|
||||
nothing.
|
||||
|
||||
|
||||
Basic Arithmetic
|
||||
----------------
|
||||
|
||||
Once you have initialized your integers, you can operate on them. The
|
||||
basic arithmetic functions on full mp_int values are:
|
||||
|
||||
mp_add(a, b, c) - computes c = a + b
|
||||
mp_sub(a, b, c) - computes c = a - b
|
||||
mp_mul(a, b, c) - computes c = a * b
|
||||
mp_sqr(a, b) - computes b = a * a
|
||||
mp_div(a, b, q, r) - computes q, r such that a = bq + r
|
||||
mp_div_2d(a, d, q, r) - computes q = a / 2^d, r = a % 2^d
|
||||
mp_expt(a, b, c) - computes c = a ** b
|
||||
mp_2expt(a, k) - computes a = 2^k
|
||||
mp_sqrt(a, c) - computes c = floor(sqrt(a))
|
||||
|
||||
The mp_div_2d() function efficiently computes division by powers of
|
||||
two. Either the q or r parameter may be NULL, in which case that
|
||||
portion of the computation will be discarded.
|
||||
|
||||
The algorithms used for some of the computations here are described in
|
||||
the following files which are included with this distribution:
|
||||
|
||||
mul.txt Describes the multiplication algorithm
|
||||
div.txt Describes the division algorithm
|
||||
expt.txt Describes the exponentiation algorithm
|
||||
sqrt.txt Describes the square-root algorithm
|
||||
square.txt Describes the squaring algorithm
|
||||
|
||||
There are single-digit versions of most of these routines, as well.
|
||||
In the following prototypes, 'd' is a single mp_digit:
|
||||
|
||||
mp_add_d(a, d, c) - computes c = a + d
|
||||
mp_sub_d(a, d, c) - computes c = a - d
|
||||
mp_mul_d(a, d, c) - computes c = a * d
|
||||
mp_mul_2(a, c) - computes c = a * 2
|
||||
mp_div_d(a, d, q, r) - computes q, r such that a = bq + r
|
||||
mp_div_2(a, c) - computes c = a / 2
|
||||
mp_expt_d(a, d, c) - computes c = a ** d
|
||||
|
||||
The mp_mul_2() and mp_div_2() functions take advantage of the internal
|
||||
representation of an mp_int to do multiplication by two more quickly
|
||||
than mp_mul_d() would. Other basic functions of an arithmetic variety
|
||||
include:
|
||||
|
||||
mp_zero(a) - assign 0 to a
|
||||
mp_neg(a, c) - negate a: c = -a
|
||||
mp_abs(a, c) - absolute value: c = |a|
|
||||
|
||||
|
||||
Comparisons
|
||||
-----------
|
||||
|
||||
Several comparison functions are provided. Each of these, unless
|
||||
otherwise specified, returns zero if the comparands are equal, < 0 if
|
||||
the first is less than the second, and > 0 if the first is greater
|
||||
than the second:
|
||||
|
||||
mp_cmp_z(a) - compare a <=> 0
|
||||
mp_cmp_d(a, d) - compare a <=> d, d is a single digit
|
||||
mp_cmp(a, b) - compare a <=> b
|
||||
mp_cmp_mag(a, b) - compare |a| <=> |b|
|
||||
mp_cmp_int(a, z) - compare a <=> z, z is a signed long integer
|
||||
mp_isodd(a) - return nonzero if odd, zero otherwise
|
||||
mp_iseven(a) - return nonzero if even, zero otherwise
|
||||
|
||||
|
||||
Modular Arithmetic
|
||||
------------------
|
||||
|
||||
Modular variations of the basic arithmetic functions are also
|
||||
supported. These are available if the MP_MODARITH parameter in
|
||||
mpi-config.h is turned on (it is by default). The modular arithmetic
|
||||
functions are:
|
||||
|
||||
mp_mod(a, m, c) - compute c = a (mod m), 0 <= c < m
|
||||
mp_mod_d(a, d, c) - compute c = a (mod d), 0 <= c < d (see below)
|
||||
mp_addmod(a, b, m, c) - compute c = (a + b) mod m
|
||||
mp_submod(a, b, m, c) - compute c = (a - b) mod m
|
||||
mp_mulmod(a, b, m, c) - compute c = (a * b) mod m
|
||||
mp_sqrmod(a, m, c) - compute c = (a * a) mod m
|
||||
mp_exptmod(a, b, m, c) - compute c = (a ** b) mod m
|
||||
mp_exptmod_d(a, d, m, c)- compute c = (a ** d) mod m
|
||||
|
||||
The mp_sqr() function squares its input argument. A call to mp_sqr(a,
|
||||
c) is identical in meaning to mp_mul(a, a, c); however, if the
|
||||
MP_SQUARE variable is set true in mpi-config.h (see below), then it
|
||||
will be implemented with a different algorithm, that is supposed to
|
||||
take advantage of the redundant computation that takes place during
|
||||
squaring. Unfortunately, some compilers result in worse performance
|
||||
on this code, so you can change the behaviour at will. There is a
|
||||
utility program "mulsqr.c" that lets you test which does better on
|
||||
your system.
|
||||
|
||||
The mp_sqrmod() function is analogous to the mp_sqr() function; it
|
||||
uses the mp_sqr() function rather than mp_mul(), and then performs the
|
||||
modular reduction. This probably won't help much unless you are doing
|
||||
a lot of them.
|
||||
|
||||
See the file 'square.txt' for a synopsis of the algorithm used.
|
||||
|
||||
Note: The mp_mod_d() function computes a modular reduction around
|
||||
---- a single digit d. The result is a single digit c.
|
||||
|
||||
Because an inverse is defined for a (mod m) if and only if (a, m) = 1
|
||||
(that is, if a and m are relatively prime), mp_invmod() may not be
|
||||
able to compute an inverse for the arguments. In this case, it
|
||||
returns the value MP_UNDEF, and does not modify c. If an inverse is
|
||||
defined, however, it returns MP_OKAY, and sets c to the value of the
|
||||
inverse (mod m).
|
||||
|
||||
See the file 'redux.txt' for a description of the modular reduction
|
||||
algorithm used by mp_exptmod().
|
||||
|
||||
|
||||
Greatest Common Divisor
|
||||
-----------------------
|
||||
|
||||
If The greates common divisor of two values can be found using one of the
|
||||
following functions:
|
||||
|
||||
mp_gcd(a, b, c) - compute c = (a, b) using binary algorithm
|
||||
mp_lcm(a, b, c) - compute c = [a, b] = ab / (a, b)
|
||||
mp_xgcd(a, b, g, x, y) - compute g, x, y so that ax + by = g = (a, b)
|
||||
|
||||
Also provided is a function to compute modular inverses, if they
|
||||
exist:
|
||||
|
||||
mp_invmod(a, m, c) - compute c = a^-1 (mod m), if it exists
|
||||
|
||||
The function mp_xgcd() computes the greatest common divisor, and also
|
||||
returns values of x and y satisfying Bezout's identity. This is used
|
||||
by mp_invmod() to find modular inverses. However, if you do not need
|
||||
these values, you will find that mp_gcd() is MUCH more efficient,
|
||||
since it doesn't need all the intermediate values that mp_xgcd()
|
||||
requires in order to compute x and y.
|
||||
|
||||
The mp_gcd() (and mp_xgcd()) functions use the binary (extended) GCD
|
||||
algorithm due to Josef Stein.
|
||||
|
||||
|
||||
Input & Output Functions
|
||||
------------------------
|
||||
|
||||
The following basic I/O routines are provided. These are present at
|
||||
all times:
|
||||
|
||||
mp_read_radix(mp, str, r) - convert a string in radix r to an mp_int
|
||||
mp_read_raw(mp, s, len) - convert a string of bytes to an mp_int
|
||||
mp_radix_size(mp, r) - return length of buffer needed by mp_toradix()
|
||||
mp_raw_size(mp) - return length of buffer needed by mp_toraw()
|
||||
mp_toradix(mp, str, r) - convert an mp_int to a string of radix r
|
||||
digits
|
||||
mp_toraw(mp, str) - convert an mp_int to a string of bytes
|
||||
mp_tovalue(ch, r) - convert ch to its value when taken as
|
||||
a radix r digit, or -1 if invalid
|
||||
mp_strerror(err) - get a string describing mp_err value 'err'
|
||||
|
||||
If you compile the MPI library with MP_IOFUNC defined, you will also
|
||||
have access to the following additional I/O function:
|
||||
|
||||
mp_print(mp, ofp) - print an mp_int as text to output stream ofp
|
||||
|
||||
Note that mp_radix_size() returns a size in bytes guaranteed to be AT
|
||||
LEAST big enough for the digits output by mp_toradix(). Because it
|
||||
uses an approximation technique to figure out how many digits will be
|
||||
needed, it may return a figure which is larger than necessary. Thus,
|
||||
the caller should not rely on the value to determine how many bytes
|
||||
will actually be written by mp_toradix(). The string mp_toradix()
|
||||
creates will be NUL terminated, so the standard C library function
|
||||
strlen() should be able to ascertain this for you, if you need it.
|
||||
|
||||
The mp_read_radix() and mp_toradix() functions support bases from 2 to
|
||||
64 inclusive. If you require more general radix conversion facilities
|
||||
than this, you will need to write them yourself (that's why mp_div_d()
|
||||
is provided, after all).
|
||||
|
||||
Note: mp_read_radix() will accept as digits either capital or
|
||||
---- lower-case letters. However, the current implementation of
|
||||
mp_toradix() only outputs upper-case letters, when writing
|
||||
bases betwee 10 and 36. The underlying code supports using
|
||||
lower-case letters, but the interface stub does not have a
|
||||
selector for it. You can add one yourself if you think it
|
||||
is worthwhile -- I do not. Bases from 36 to 64 use lower-
|
||||
case letters as distinct from upper-case. Bases 63 and
|
||||
64 use the characters '+' and '/' as digits.
|
||||
|
||||
Note also that compiling with MP_IOFUNC defined will cause
|
||||
inclusion of <stdio.h>, so if you are trying to write code
|
||||
which does not depend on the standard C library, you will
|
||||
probably want to avoid this option. This is needed because
|
||||
the mp_print() function takes a standard library FILE * as
|
||||
one of its parameters, and uses the fprintf() function.
|
||||
|
||||
The mp_toraw() function converts the integer to a sequence of bytes,
|
||||
in big-endian ordering (most-significant byte first). Assuming your
|
||||
bytes are 8 bits wide, this corresponds to base 256. The sign is
|
||||
encoded as a single leading byte, whose value is 0 for zero or
|
||||
positive values, or 1 for negative values. The mp_read_raw() function
|
||||
reverses this process -- it takes a buffer of bytes, interprets the
|
||||
first as a sign indicator (0 = zero/positive, nonzero = negative), and
|
||||
the rest as a sequence of 1-byte digits in big-endian ordering.
|
||||
|
||||
The mp_raw_size() function returns the exact number of bytes required
|
||||
to store the given integer in "raw" format (as described in the
|
||||
previous paragraph). Zero is returned in case of error; a valid
|
||||
integer will require at least three bytes of storage.
|
||||
|
||||
In previous versions of the MPI library, an "external representation
|
||||
format" was supported. This was removed, however, because I found I
|
||||
was never using it, it was not as portable as I would have liked, and
|
||||
I decided it was a waste of space.
|
||||
|
||||
|
||||
Other Functions
|
||||
---------------
|
||||
|
||||
The files 'mpprime.h' and 'mpprime.c' define some routines which are
|
||||
useful for divisibility testing and probabilistic primality testing.
|
||||
The routines defined are:
|
||||
|
||||
mpp_divis(a, b) - is a divisible by b?
|
||||
mpp_divis_d(a, d) - is a divisible by digit d?
|
||||
mpp_random(a) - set a to random value at current precision
|
||||
mpp_random_size(a, prec) - set a to random value at given precision
|
||||
|
||||
Note: The mpp_random() and mpp_random_size() functions use the C
|
||||
---- library's rand() function to generate random values. It is
|
||||
up to the caller to seed this generator before it is called.
|
||||
These functions are not suitable for generating quantities
|
||||
requiring cryptographic-quality randomness; they are intended
|
||||
primarily for use in primality testing.
|
||||
|
||||
Note too that the MPI library does not call srand(), so your
|
||||
application should do this, if you ever want the sequence
|
||||
to change.
|
||||
|
||||
mpp_divis_vector(a, v, s, w) - is a divisible by any of the s digits
|
||||
in v? If so, let w be the index of
|
||||
that digit
|
||||
|
||||
mpp_divis_primes(a, np) - is a divisible by any of the first np
|
||||
primes? If so, set np to the prime
|
||||
which divided a.
|
||||
|
||||
mpp_fermat(a, d) - test if w^a = w (mod a). If so,
|
||||
returns MP_YES, otherwise MP_NO.
|
||||
|
||||
mpp_pprime(a, nt) - perform nt iterations of the Rabin-
|
||||
Miller probabilistic primality test
|
||||
on a. Returns MP_YES if all tests
|
||||
passed, or MP_NO if any test fails.
|
||||
|
||||
The mpp_fermat() function works based on Fermat's little theorem, a
|
||||
consequence of which is that if p is a prime, and (w, p) = 1, then:
|
||||
|
||||
w^p = w (mod p)
|
||||
|
||||
Put another way, if w^p != w (mod p), then p is not prime. The test
|
||||
is expensive to compute, but it helps to quickly eliminate an enormous
|
||||
class of composite numbers prior to Rabin-Miller testing.
|
||||
|
||||
Building the Library
|
||||
--------------------
|
||||
|
||||
The MPI library is designed to be as self-contained as possible. You
|
||||
should be able to compile it with your favourite ANSI C compiler, and
|
||||
link it into your program directly. If you are on a Unix system using
|
||||
the GNU C compiler (gcc), the following should work:
|
||||
|
||||
% gcc -ansi -pedantic -Wall -O2 -c mpi.c
|
||||
|
||||
The file 'mpi-config.h' defines several configurable parameters for
|
||||
the library, which you can adjust to suit your application. At the
|
||||
time of this writing, the available options are:
|
||||
|
||||
MP_IOFUNC - Define true to include the mp_print() function,
|
||||
which is moderately useful for debugging. This
|
||||
implicitly includes <stdio.h>.
|
||||
|
||||
MP_MODARITH - Define true to include the modular arithmetic
|
||||
functions. If you don't need modular arithmetic
|
||||
in your application, you can set this to zero to
|
||||
leave out all the modular routines.
|
||||
|
||||
MP_NUMTH - Define true to include number theoretic functions
|
||||
such as mp_gcd(), mp_lcm(), and mp_invmod().
|
||||
|
||||
MP_LOGTAB - If true, the file "logtab.h" is included, which
|
||||
is basically a static table of base 2 logarithms.
|
||||
These are used to compute how big the buffers for
|
||||
radix conversion need to be. If you set this false,
|
||||
the library includes <math.h> and uses log(). This
|
||||
typically forces you to link against math libraries.
|
||||
|
||||
MP_MEMSET - If true, use memset() to zero buffers. If you run
|
||||
into weird alignment related bugs, set this to zero
|
||||
and an explicit loop will be used.
|
||||
|
||||
MP_MEMCPY - If true, use memcpy() to copy buffers. If you run
|
||||
into weird alignment bugs, set this to zero and an
|
||||
explicit loop will be used.
|
||||
|
||||
MP_CRYPTO - If true, whenever arrays of digits are free'd, they
|
||||
are zeroed first. This is useful if you're using
|
||||
the library in a cryptographic environment; however,
|
||||
it does add overhead to each free operation. For
|
||||
performance, if you don't care about zeroing your
|
||||
buffers, set this to false.
|
||||
|
||||
MP_ARGCHK - Set to 0, 1, or 2. This defines how the argument
|
||||
checking macro, ARGCHK(), gets expanded. If this
|
||||
is set to zero, ARGCHK() expands to nothing; no
|
||||
argument checks are performed. If this is 1, the
|
||||
ARGCHK() macro expands to code that returns MP_BADARG
|
||||
or similar at runtime. If it is 2, ARGCHK() expands
|
||||
to an assert() call that aborts the program on a
|
||||
bad input.
|
||||
|
||||
MP_DEBUG - Turns on debugging output. This is probably not at
|
||||
all useful unless you are debugging the library. It
|
||||
tends to spit out a LOT of output.
|
||||
|
||||
MP_DEFPREC - The default precision of a newly-created mp_int, in
|
||||
digits. The precision can be changed at runtime by
|
||||
the mp_set_prec() function, but this is its initial
|
||||
value.
|
||||
|
||||
MP_SQUARE - If this is set to a nonzero value, the mp_sqr()
|
||||
function will use an alternate algorithm that takes
|
||||
advantage of the redundant inner product computation
|
||||
when both multiplicands are identical. Unfortunately,
|
||||
with some compilers this is actually SLOWER than just
|
||||
calling mp_mul() with the same argument twice. So
|
||||
if you set MP_SQUARE to zero, mp_sqr() will be expan-
|
||||
ded into a call to mp_mul(). This applies to all
|
||||
the uses of mp_sqr(), including mp_sqrmod() and the
|
||||
internal calls to s_mp_sqr() inside mpi.c
|
||||
|
||||
The program 'mulsqr' (mulsqr.c) can be used to test
|
||||
which works best for your configuration. Set up the
|
||||
CC and CFLAGS variables in the Makefile, then type:
|
||||
|
||||
make mulsqr
|
||||
|
||||
Invoke it with arguments similar to the following:
|
||||
|
||||
mulsqr 25000 1024
|
||||
|
||||
That is, 25000 products computed on 1024-bit values.
|
||||
The output will compare the two timings, and recommend
|
||||
a setting for MP_SQUARE. It is off by default.
|
||||
|
||||
If you would like to use the mp_print() function (see above), be sure
|
||||
to define MP_IOFUNC in mpi-config.h. Many of the test drivers in the
|
||||
'tests' subdirectory expect this to be defined (although the test
|
||||
driver 'mpi-test' doesn't need it)
|
||||
|
||||
The Makefile which comes with the library should take care of building
|
||||
the library for you, if you have set the CC and CFLAGS variables at
|
||||
the top of the file appropriately. By default, they are set up to
|
||||
use the GNU C compiler:
|
||||
|
||||
CC=gcc
|
||||
CFLAGS=-ansi -pedantic -Wall -O2
|
||||
|
||||
If all goes well, the library should compile without warnings using
|
||||
this combination. You should, of course, make whatever adjustments
|
||||
you find necessary.
|
||||
|
||||
The MPI library distribution comes with several additional programs
|
||||
which are intended to demonstrate the use of the library, and provide
|
||||
a framework for testing it. There are a handful of test driver
|
||||
programs, in the files named 'mptest-X.c', where X is a digit. Also,
|
||||
there are some simple command-line utilities (in the 'utils'
|
||||
directory) for manipulating large numbers. These include:
|
||||
|
||||
basecvt.c A radix-conversion program, supporting bases from
|
||||
2 to 64 inclusive.
|
||||
|
||||
bbsrand.c A BBS (quadratic residue) pseudo-random number
|
||||
generator. The file 'bbsrand.c' is just the driver
|
||||
for the program; the real code lives in the files
|
||||
'bbs_rand.h' and 'bbs_rand.c'
|
||||
|
||||
dec2hex.c Converts decimal to hexadecimal
|
||||
|
||||
gcd.c Computes the greatest common divisor of two values.
|
||||
If invoked as 'xgcd', also computes constants x and
|
||||
y such that (a, b) = ax + by, in accordance with
|
||||
Bezout's identity.
|
||||
|
||||
hex2dec.c Converts hexadecimal to decimal
|
||||
|
||||
invmod.c Computes modular inverses
|
||||
|
||||
isprime.c Performs the Rabin-Miller probabilistic primality
|
||||
test on a number. Values which fail this test are
|
||||
definitely composite, and those which pass are very
|
||||
likely to be prime (although there are no guarantees)
|
||||
|
||||
lap.c Computes the order (least annihilating power) of
|
||||
a value v modulo m. Very dumb algorithm.
|
||||
|
||||
primegen.c Generates large (probable) primes.
|
||||
|
||||
prng.c A pseudo-random number generator based on the
|
||||
BBS generator code in 'bbs_rand.c'
|
||||
|
||||
sieve.c Implements the Sieve of Eratosthenes, using a big
|
||||
bitmap, to generate a list of prime numbers.
|
||||
|
||||
fact.c Computes the factorial of an arbitrary precision
|
||||
integer (iterative).
|
||||
|
||||
exptmod.c Computes arbitrary precision modular exponentiation
|
||||
from the command line (exptmod a b m -> a^b (mod m))
|
||||
|
||||
Most of these can be built from the Makefile that comes with the
|
||||
library. Try 'make tools', if your environment supports it. (If you
|
||||
are compiling on a Macintosh, I'm afraid you'll have to build them by
|
||||
hand -- fortunately, this is not difficult -- the library itself
|
||||
should compile just fine under Metrowerks CodeWarrior).
|
||||
|
||||
|
||||
Testing the Library
|
||||
-------------------
|
||||
|
||||
Automatic test vectors are included, in the form of a program called
|
||||
'mpi-test'. To build this program and run all the tests, simply
|
||||
invoke the shell script 'all-tests'. If all the tests pass, you
|
||||
should see a message:
|
||||
|
||||
All tests passed
|
||||
|
||||
If something went wrong, you'll get:
|
||||
|
||||
One or more tests failed.
|
||||
|
||||
If this happens, scan back through the preceding lines, to see which
|
||||
test failed. Any failure indicates a bug in the library, which needs
|
||||
to be fixed before it will give accurate results. If you get any such
|
||||
thing, please let me know, and I'll try to fix it. Please let me know
|
||||
what platform and compiler you were using, as well as which test
|
||||
failed. If a reason for failure was given, please send me that text
|
||||
as well.
|
||||
|
||||
If you're on a system such as the Macintosh, where the standard Unix
|
||||
build tools don't work, you can build the 'mpi-test' program manually,
|
||||
and run it by hand. This is tedious and obnoxious, sorry.
|
||||
|
||||
Further manual testing can be performed by building the manual testing
|
||||
programs, whose source is found in the 'tests' subdirectory. Each
|
||||
test is in a source file called 'mptest-X.c'. The Makefile contains a
|
||||
target to build all of them at once:
|
||||
|
||||
make tests
|
||||
|
||||
Read the comments at the top of each source file to see what the
|
||||
driver is supposed to test. You probably don't need to do this; these
|
||||
programs were only written to help me as I was developing the library.
|
||||
|
||||
The relevant files are:
|
||||
|
||||
mpi-test.c The source for the test driver
|
||||
|
||||
make-test-arrays A Perl script to generate some of the internal
|
||||
data structures used by mpi-test.c
|
||||
|
||||
test-arrays.txt The source file for make-test-arrays
|
||||
|
||||
all-tests A Bourne shell script which runs all the
|
||||
tests in the mpi-test suite
|
||||
|
||||
Running 'make mpi-test' should build the mpi-test program. If you
|
||||
cannot use make, here is what needs to be done:
|
||||
|
||||
(1) Use 'make-test-arrays' to generate the file 'test-info.c' from
|
||||
the 'test-arrays.txt' file. Since Perl can be found everywhere,
|
||||
even on the Macintosh, this should be no trouble. Under Unix,
|
||||
this looks like:
|
||||
|
||||
make-test-arrays test-arrays.txt > test-info.c
|
||||
|
||||
(2) Build the MPI library:
|
||||
|
||||
gcc -ansi -pedantic -Wall -c mpi.c
|
||||
|
||||
(3) Build the mpi-test program:
|
||||
|
||||
gcc -ansi -pedantic -Wall -o mpi-test mpi.o mpi-test.c
|
||||
|
||||
When you've got mpi-test, you can use 'all-tests' to run all the tests
|
||||
made available by mpi-test. If any of them fail, there should be a
|
||||
diagnostic indicating what went wrong. These are fairly high-level
|
||||
diagnostics, and won't really help you debug the problem; they're
|
||||
simply intended to help you isolate which function caused the problem.
|
||||
If you encounter a problem of this sort, feel free to e-mail me, and I
|
||||
will certainly attempt to help you debug it.
|
||||
|
||||
Note: Several of the tests hard-wired into 'mpi-test' operate under
|
||||
---- the assumption that you are using at least a 16-bit mp_digit
|
||||
type. If that is not true, several tests might fail, because
|
||||
of range problems with the maximum digit value.
|
||||
|
||||
If you are using an 8-bit digit, you will also need to
|
||||
modify the code for mp_read_raw(), which assumes that
|
||||
multiplication by 256 can be done with mp_mul_d(), a
|
||||
fact that fails when DIGIT_MAX is 255. You can replace
|
||||
the call with s_mp_lshd(), which will give you the same
|
||||
effect, and without doing as much work. :)

The algorithms used in this library were drawn primarily from Volume
|
||||
2 of Donald Knuth's magnum opus, _The Art of Computer Programming_,
|
||||
"Semi-Numerical Methods". Barrett's algorithm for modular reduction
|
||||
came from Menezes, Oorschot, and Vanstone's _Handbook of Applied
|
||||
Cryptography_, Chapter 14.
|

Thanks are due to Tom St. Denis, for finding an obnoxious sign-related
|
||||
bug in mp_read_raw() that made things break on platforms which use
|

signed chars.

=head1 NAME
|
||||
|
||||
basecvt - radix conversion for arbitrary precision integers
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
basecvt <ibase> <obase> [values]
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
The B<basecvt> program is a command-line tool for converting integers
|
||||
of arbitrary precision from one radix to another. The current version
|
||||
supports radix values from 2 (binary) to 64, inclusive. The first two
|
||||
command line arguments specify the input and output radix, in base 10.
|
||||
Any further arguments are taken to be integers notated in the input
|
||||
radix, and these are converted to the output radix. The output is
|
||||
written, one integer per line, to standard output.
|
||||
|
||||
When reading integers, only digits considered "valid" for the input
|
||||
radix are considered. Processing of an integer terminates when an
|
||||
invalid input digit is encountered. So, for example, if you set the
|
||||
input radix to 10 and enter '10ACF', B<basecvt> would assume that you
|
||||
had entered '10' and ignore the rest of the string.
|
||||
|
||||
If no values are provided, no output is written, but the program
|
||||
simply terminates with a zero exit status. Error diagnostics are
|
||||
written to standard error in the event of out-of-range radix
|
||||
specifications. Regardless of the actual values of the input and
|
||||
output radix, the radix arguments are taken to be in base 10 (decimal)
|
||||
notation.
|
||||
|
||||
=head1 DIGITS
|
||||
|
||||
For radices from 2-10, standard ASCII decimal digits 0-9 are used for
|
||||
both input and output. For radices from 11-36, the ASCII letters A-Z
|
||||
are also included, following the convention used in hexadecimal. In
|
||||
this range, input is accepted in either upper or lower case, although
|
||||
on output only lower-case letters are used.
|
||||
|
||||
For radices from 37-62, the output includes both upper- and lower-case
|
||||
ASCII letters, and case matters. In this range, case is distinguished
|
||||
both for input and for output values.
|
||||
|
||||
For radices 63 and 64, the characters '+' (plus) and '/' (forward
|
||||
solidus) are also used. These are derived from the MIME base64
|
||||
encoding scheme. The overall encoding is not the same as base64,
|
||||
because the ASCII digits are used for the bottom of the range, and the
|
||||
letters are shifted upward; however, the output will consist of the
|
||||
same character set.
|
||||
|
||||
This input and output behaviour is inherited from the MPI library used
|
||||
by B<basecvt>, and so is not configurable at runtime.

Division
|
||||
|
||||
This describes the division algorithm used by the MPI library.
|
||||
|
||||
Input: a, b; a > b
|
||||
Compute: Q, R; a = Qb + R
|
||||
|
||||
The input numbers are normalized so that the high-order digit of b is
|
||||
at least half the radix. This guarantees that we have a reasonable
|
||||
way to guess at the digits of the quotient (this method was taken from
|
||||
Knuth, vol. 2, with adaptations).
|
||||
|
||||
To normalize, test the high-order digit of b. If it is less than half
|
||||
the radix, multiply both a and b by d, where:
|
||||
|
||||
radix - 1
|
||||
d = -----------
|
||||
bmax + 1
|
||||
|
||||
...where bmax is the high-order digit of b. Otherwise, set d = 1.
|
||||
|
||||
Given normalize values for a and b, let the notation a[n] denote the
|
||||
nth digit of a. Let #a be the number of significant figures of a (not
|
||||
including any leading zeroes).
|
||||
|
||||
Let R = 0
|
||||
Let p = #a - 1
|
||||
|
||||
while(p >= 0)
|
||||
do
|
||||
R = (R * radix) + a[p]
|
||||
p = p - 1
|
||||
while(R < b and p >= 0)
|
||||
|
||||
if(R < b)
|
||||
break
|
||||
|
||||
q = (R[#R - 1] * radix) + R[#R - 2]
|
||||
q = q / b[#b - 1]
|
||||
|
||||
T = b * q
|
||||
|
||||
while(T > L)
|
||||
q = q - 1
|
||||
T = T - b
|
||||
endwhile
|
||||
|
||||
L = L - T
|
||||
|
||||
Q = (Q * radix) + q
|
||||
|
||||
endwhile
|
||||
|
||||
At this point, Q is the quotient, and R is the normalized remainder.
|
||||
To denormalize R, compute:
|
||||
|
||||
R = (R / d)
|
||||
|
||||
At this point, you are finished.

Exponentiation
|
||||
|
||||
For exponentiation, the MPI library uses a simple and fairly standard
|
||||
square-and-multiply method. The algorithm is this:
|
||||
|
||||
Input: a, b
|
||||
Output: a ** b
|
||||
|
||||
s = 1
|
||||
|
||||
while(b != 0)
|
||||
if(b is odd)
|
||||
s = s * a
|
||||
endif
|
||||
|
||||
b = b / 2
|
||||
|
||||
x = x * x
|
||||
endwhile
|
||||
|
||||
return s
|
||||
|
||||
The modular exponentiation is done the same way, except replacing:
|
||||
|
||||
s = s * a
|
||||
|
||||
with
|
||||
s = (s * a) mod m
|
||||
|
||||
and replacing
|
||||
|
||||
x = x * x
|
||||
|
||||
with
|
||||
|
||||
x = (x * x) mod m
|
||||
|
||||
Here is a sample exponentiation using the MPI library, as compared to
|
||||
the same problem solved by the Unix 'bc' program on my system:

isprime - probabilistic primality testing
|
||||
|

=head1 SYNOPSIS
|
||||
|
||||
isprime <a>
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
The B<isprime> program attempts to determine whether the arbitrary
|
||||
precision integer I<a> is prime. It first tests I<a> for divisibility
|
||||
by the first 170 or so small primes, and assuming I<a> is not
|
||||
divisible by any of these, applies 15 iterations of the Rabin-Miller
|
||||
probabilistic primality test.
|
||||
|
||||
If the program discovers that the number is composite, it will print:
|
||||
|
||||
Not prime (reason)
|
||||
|
||||
Where I<reason> is either:
|
||||
|
||||
divisible by small prime x
|
||||
|
||||
Or:
|
||||
|
||||
failed nth pseudoprime test
|
||||
|
||||
In the first case, I<x> indicates the first small prime factor that
|
||||
was found. In the second case, I<n> indicates which of the
|
||||
pseudoprime tests failed (numbered from 1)
|
||||
|
||||
If this happens, the number is definitely not prime. However, if the
|
||||
number succeeds, this message results:
|
||||
|
||||
Probably prime, 1 in 4^15 chance of false positive
|
||||
|
||||
If this happens, the number is prime with very high probability, but
|
||||
its primality has not been absolutely proven, only demonstrated to a
|
||||
very convincing degree.
|
||||
|
||||
The value I<a> can be input in standard decimal notation, or, if it is
|
||||
prefixed with I<Ox>, it will be read as hexadecimal.
|
||||
|
||||
=head1 ENVIRONMENT
|
||||
|
||||
You can control how many iterations of Rabin-Miller are performed on
|
||||
the candidate number by setting the I<RM_TESTS> environment variable
|
||||
to an integer value before starting up B<isprime>. This will change
|
||||
the output slightly if the number passes all the tests.

|
||||
|
||||
The B<mpi-test> program is a general unit test driver for the MPI
|
||||
library. It is used to verify that the library works as it is
|
||||
supposed to on your architecture. As with most such things, passing
|
||||
all the tests in B<mpi-test> does not guarantee the code is correct,
|
||||
but if any of them fail, there are certainly problems.
|
||||
|
||||
Each major function of the library can be tested individually. For a
|
||||
list of the test suites understood by B<mpi-test>, run it with the
|
||||
I<list> command line option:
|
||||
|
||||
mpi-test list
|
||||
|
||||
This will display a list of the available test suites and a brief
|
||||
synopsis of what each one does. For a brief overview of this
|
||||
document, run B<mpi-test> I<help>.
|
||||
|
||||
B<mpi-test> exits with a zero status if the selected test succeeds, or
|
||||
a nonzero status if it fails. If a I<suite-name> which is not
|
||||
understood by B<mpi-test> is given, a diagnostic is printed to the
|
||||
standard error, and the program exits with a result code of 2. If a
|
||||
test fails, the result code will be 1, and a diagnostic is ordinarily
|
||||
printed to the standard error. However, if the I<quiet> option is
|
||||
provided, these diagnostics will be suppressed.
|
||||
|
||||
=head1 RESTRICTIONS
|
||||
|
||||
Only a few canned test cases are provided. The solutions have been
|
||||
verified using the GNU bc(1) program, so bugs there may cause problems
|
||||
here; however, this is very unlikely, so if a test fails, it is almost
|
||||
certainly my fault, not bc(1)'s.

Multiplication
|
||||
|
||||
This describes the multiplication algorithm used by the MPI library.
|
||||
|
||||
This is basically a standard "schoolbook" algorithm. It is slow --
|
||||
O(mn) for m = #a, n = #b -- but easy to implement and verify.
|
||||
Basically, we run two nested loops, as illustrated here (R is the
|
||||
radix):
|
||||
|
||||
k = 0
|
||||
for j <- 0 to (#b - 1)
|
||||
for i <- 0 to (#a - 1)
|
||||
w = (a[j] * b[i]) + k + c[i+j]
|
||||
c[i+j] = w mod R
|
||||
k = w div R
|
||||
endfor
|
||||
c[i+j] = k;
|
||||
k = 0;
|
||||
endfor
|
||||
|
||||
It is necessary that 'w' have room for at least two radix R digits.
|
||||
The product of any two digits in radix R is at most:
|
||||
|
||||
(R - 1)(R - 1) = R^2 - 2R + 1
|
||||
|
||||
Since a two-digit radix-R number can hold R^2 - 1 distinct values,
|
||||
this insures that the product will fit into the two-digit register.
|
||||
|
||||
To insure that two digits is enough for w, we must also show that
|
||||
there is room for the carry-in from the previous multiplication, and
|
||||
the current value of the product digit that is being recomputed.
|
||||
Assuming each of these may be as big as R - 1 (and no larger,
|
||||
certainly), two digits will be enough if and only if:
|
||||
|
||||
(R^2 - 2R + 1) + 2(R - 1) <= R^2 - 1
|
||||
|
||||
Solving this equation shows that, indeed, this is the case:
|

|
||||
R^2 - 2R + 1 + 2R - 2 <= R^2 - 1
|
||||
|
||||
R^2 - 1 <= R^2 - 1
|
||||
|
||||
This suggests that a good radix would be one more than the largest
|
||||
value that can be held in half a machine word -- so, for example, as
|
||||
in this implementation, where we used a radix of 65536 on a machine
|
||||
with 4-byte words. Another advantage of a radix of this sort is that
|
||||
binary-level operations are easy on numbers in this representation.
|
||||
|
||||
Here's an example multiplication worked out longhand in radix-10,
|
||||
using the above algorithm:
|
||||
|
||||
a = 999
|
||||
b = x 999
|
||||
-------------
|
||||
p = 98001
|
||||
|
||||
w = (a[jx] * b[ix]) + kin + c[ix + jx]
|
||||
c[ix+jx] = w % RADIX

||||
k = w / RADIX

This file describes how pi is computed by the program in 'pi.c' (see
|
||||
the utils subdirectory).
|
||||
|
||||
Basically, we use Machin's formula, which is what everyone in the
|
||||
world uses as a simple method for computing approximations to pi.
|
||||
This works for up to a few thousand digits without too much effort.
|
||||
Beyond that, though, it gets too slow.
|
||||
|
||||
Machin's formula states:
|
||||
|
||||
pi := 16 * arctan(1/5) - 4 * arctan(1/239)
|
||||
|
||||
We compute this in integer arithmetic by first multiplying everything
|
||||
through by 10^d, where 'd' is the number of digits of pi we wanted to
|
||||
compute. It turns out, the last few digits will be wrong, but the
|
||||
number that are wrong is usually very small (ordinarly only 2-3).
|
||||
Having done this, we compute the arctan() function using the formula:
|
||||
|
||||
1 1 1 1 1
|
||||
arctan(1/x) := --- - ----- + ----- - ----- + ----- - ...
|
||||
x 3 x^3 5 x^5 7 x^7 9 x^9
|
||||
|
||||
This is done iteratively by computing the first term manually, and
|
||||
then iteratively dividing x^2 and k, where k = 3, 5, 7, ... out of the
|
||||
current figure. This is then added to (or subtracted from) a running
|
||||
sum, as appropriate. The iteration continues until we overflow our
|
||||
available precision and the current figure goes to zero under integer
|
||||
division. At that point, we're finished.
|
||||
|
||||
Actually, we get a couple extra bits of precision out of the fact that
|
||||
we know we're computing y * arctan(1/x), by setting up the multiplier
|
||||
as:
|
||||
|
||||
y * 10^d
|
||||
|
||||
... instead of just 10^d. There is also a bit of cleverness in how
|
||||
the loop is constructed, to avoid special-casing the first term.
|
||||
Check out the code for arctan() in 'pi.c', if you are interested in
|
||||
seeing how it is set up.
|
||||
|
||||
Thanks to Jason P. for this algorithm, which I assembled from notes
|
||||
and programs found on his cool "Pile of Pi Programs" page, at:
|
||||
|
||||
http://www.isr.umd.edu/~jasonp/pipage.html
|
||||
|
||||
Thanks also to Henrik Johansson <Henrik.Johansson@Nexus.Comm.SE>, from
|
||||
whose pi program I borrowed the clever idea of pre-multiplying by x in
|
||||
order to avoid a special case on the loop iteration.

prng - pseudo-random number generator
|

|
||||
=head1 SYNOPSIS
|
||||
|
||||
prng [count]
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
B<Prng> generates 32-bit pseudo-random integers using the
|
||||
Blum-Blum-Shub (BBS) quadratic residue generator. It is seeded using
|
||||
the standard C library's rand() function, which itself seeded from the
|
||||
system clock and the process ID number. Thus, the values generated
|
||||
are not particularly useful for cryptographic applications, but they
|
||||
are in general much better than the typical output of the usual
|
||||
multiplicative congruency generator used by most runtime libraries.
|
||||
|
||||
You may optionally specify how many random values should be generated
|
||||
by giving a I<count> argument on the command line. If you do not
|
||||
specify a count, only one random value will be generated. The results
|
||||
are output to the standard output in decimal notation, one value per
|
||||
line.
|
||||
|
||||
=head1 RESTRICTIONS
|
||||
|
||||
As stated above, B<prng> uses the C library's rand() function to seed
|
||||
the generator, so it is not terribly suitable for cryptographic
|
||||
applications. Also note that each time you run the program, a new
|
||||
seed is generated, so it is better to run it once with a I<count>
|
||||
parameter than it is to run it multiple times to generate several
|
||||
values.

Modular Reduction
|
||||
|
||||
Usually, modular reduction is accomplished by long division, using the
|
||||
mp_div() or mp_mod() functions. However, when performing modular
|
||||
exponentiation, you spend a lot of time reducing by the same modulus
|
||||
again and again. For this purpose, doing a full division for each
|
||||
multiplication is quite inefficient.
|
||||
|
||||
For this reason, the mp_exptmod() function does not perform modular
|
||||
reductions in the usual way, but instead takes advantage of an
|
||||
algorithm due to Barrett, as described by Menezes, Oorschot and
|
||||
VanStone in their book _Handbook of Applied Cryptography_, published
|
||||
by the CRC Press (see Chapter 14 for details). This method reduces
|
||||
most of the computation of reduction to efficient shifting and masking
|
||||
operations, and avoids the multiple-precision division entirely.
|
||||
|
||||
Here is a brief synopsis of Barrett reduction, as it is implemented in
|
||||
this library.
|
||||
|
||||
Let b denote the radix of the computation (one more than the maximum
|
||||
value that can be denoted by an mp_digit). Let m be the modulus, and
|
||||
let k be the number of significant digits of m. Let x be the value to
|
||||
be reduced modulo m. By the Division Theorem, there exist unique
|
||||
integers Q and R such that:
|
||||
|
||||
x = Qm + R, 0 <= R < m
|
||||
|
||||
Barrett reduction takes advantage of the fact that you can easily
|
||||
approximate Q to within two, given a value M such that:
|
||||
|
||||
2k
|
||||
b
|
||||
M = floor( ----- )
|
||||
m
|
||||
|
||||
Computation of M requires a full-precision division step, so if you
|
||||
are only doing a single reduction by m, you gain no advantage.
|
||||
However, when multiple reductions by the same m are required, this
|
||||
division need only be done once, beforehand. Using this, we can use
|
||||
the following equation to compute Q', an approximation of Q:
|
||||
|
||||
x
|
||||
floor( ------ ) M
|
||||
k-1
|
||||
b
|
||||
Q' = floor( ----------------- )
|
||||
k+1
|
||||
b
|
||||
|
||||
The divisions by b^(k-1) and b^(k+1) and the floor() functions can be
|
||||
efficiently implemented with shifts and masks, leaving only a single
|
||||
multiplication to be performed to get this approximation. It can be
|
||||
shown that Q - 2 <= Q' <= Q, so in the worst case, we can get out with
|
||||
two additional subtractions to bring the value into line with the
|
||||
actual value of Q.
|
||||
|
||||
Once we've got Q', we basically multiply that by m and subtract from
|
||||
x, yielding:
|
||||
|
||||
x - Q'm = Qm + R - Q'm
|
||||
|
||||
Since we know the constraint on Q', this is one of:
|
||||
|
||||
R
|
||||
m + R
|
||||
2m + R
|
||||
|
||||
Since R < m by the Division Theorem, we can simply subtract off m
|
||||
until we get a value in the correct range, which will happen with no
|
||||
more than 2 subtractions:
|
||||
|
||||
v = x - Q'm
|
||||
|
||||
while(v >= m)
|
||||
v = v - m
|
||||
endwhile
|
||||
|
||||
|
||||
In random performance trials, modular exponentiation using this method
|
||||
of reduction gave around a 40% speedup over using the division for
|
||||
reduction.

Square Root
|
||||
|
||||
A simple iterative algorithm is used to compute the greatest integer
|
||||
less than or equal to the square root. Essentially, this is Newton's
|
||||
linear approximation, computed by finding successive values of the
|
||||
equation:
|
||||
|
||||
x[k]^2 - V
|
||||
x[k+1] = x[k] - ------------
|
||||
2 x[k]
|
||||
|
||||
...where V is the value for which the square root is being sought. In
|
||||
essence, what is happening here is that we guess a value for the
|
||||
square root, then figure out how far off we were by squaring our guess
|
||||
and subtracting the target. Using this value, we compute a linear
|
||||
approximation for the error, and adjust the "guess". We keep doing
|
||||
this until the precision gets low enough that the above equation
|
||||
yields a quotient of zero. At this point, our last guess is one
|
||||
greater than the square root we're seeking.
|
||||
|
||||
The initial guess is computed by dividing V by 4, which is a heuristic
|
||||
I have found to be fairly good on average. This also has the
|
||||
advantage of being very easy to compute efficiently, even for large
|
||||
values.
|
||||
|
||||
So, the resulting algorithm works as follows:
|
||||
|
||||
x = V / 4 /* compute initial guess */
|
||||
|
||||
loop
|
||||
t = (x * x) - V /* Compute absolute error */
|
||||
u = 2 * x /* Adjust by tangent slope */
|
||||
t = t / u
|
||||
|
||||
/* Loop is done if error is zero */
|
||||
if(t == 0)
|
||||
break
|
||||
|
||||
/* Adjust guess by error term */
|
||||
x = x - t
|
||||
end
|
||||
|
||||
x = x - 1
|
||||
|
||||
The result of the computation is the value of x.

Squaring Algorithm
|
||||
|
||||
When you are squaring a value, you can take advantage of the fact that
|
||||
half the multiplications performed by the more general multiplication
|
||||
algorithm (see 'mul.txt' for a description) are redundant when the
|
||||
multiplicand equals the multiplier.
|
||||
|
||||
In particular, the modified algorithm is:
|
||||
|
||||
k = 0
|
||||
for j <- 0 to (#a - 1)
|
||||
w = c[2*j] + (a[j] ^ 2);
|
||||
k = w div R
|
||||
|
||||
for i <- j+1 to (#a - 1)
|
||||
w = (2 * a[j] * a[i]) + k + c[i+j]
|
||||
c[i+j] = w mod R
|
||||
k = w div R
|
||||
endfor
|
||||
c[i+j] = k;
|
||||
k = 0;
|
||||
endfor
|
||||
|
||||
On the surface, this looks identical to the multiplication algorithm;
|
||||
however, note the following differences:
|
||||
|
||||
- precomputation of the leading term in the outer loop
|
||||
|
||||
- i runs from j+1 instead of from zero
|
||||
|
||||
- doubling of a[i] * a[j] in the inner product
|
||||
|
||||
Unfortunately, the construction of the inner product is such that we
|
||||
need more than two digits to represent the inner product, in some
|
||||
cases. In a C implementation, this means that some gymnastics must be
|
||||
performed in order to handle overflow, for which C has no direct
|
||||
abstraction. We do this by observing the following:
|
||||
|
||||
If we have multiplied a[i] and a[j], and the product is more than half
|
||||
the maximum value expressible in two digits, then doubling this result
|
||||
will overflow into a third digit. If this occurs, we take note of the
|
||||
overflow, and double it anyway -- C integer arithmetic ignores
|
||||
overflow, so the two digits we get back should still be valid, modulo
|
||||
the overflow.
|
||||
|
||||
Having doubled this value, we now have to add in the remainders and
|
||||
the digits already computed by earlier steps. If we did not overflow
|
||||
in the previous step, we might still cause an overflow here. That
|
||||
will happen whenever the maximum value expressible in two digits, less
|
||||
the amount we have to add, is greater than the result of the previous
|
||||
step. Thus, the overflow computation is:
|
||||
|
||||
|
||||
u = 0
|
||||
w = a[i] * a[j]
|
||||
|
||||
if(w > (R - 1)/ 2)
|
||||
u = 1;
|
||||
|
||||
w = w * 2
|
||||
v = c[i + j] + k
|
||||
|
||||
if(u == 0 && (R - 1 - v) < w)
|
||||
u = 1
|
||||
|
||||
If there is an overflow, u will be 1, otherwise u will be 0. The rest
|
||||
of the parameters are the same as they are in the above description.

Timings are given in seconds, computed using the C library's clock()
|
||||
function. The first column gives the hardware and compiler
|
||||
configuration used for the test. The second column indicates the
|
||||
number of tests that were aggregated to get the statistics for that
|
||||
size. These were compiled using 16 bit digits.
|
||||
|
||||
Source data were generated randomly using a fixed seed, so they should
|
||||
be internally consistent, but may vary on different systems depending
|
||||
on the C library. Also, since the resolution of the timer accessed by
|
||||
clock() varies, there may be some variance in the precision of these
|
||||
measurements.

*
|
||||
* This PA-RISC 2.0 function computes the product of two unsigned integers,
|
||||
* and adds the result to a previously computed integer. The multiplicand
|
||||
* is a 512-bit (64-byte, eight doubleword) unsigned integer, stored in
|
||||
* memory in little-double-wordian order. The multiplier is an unsigned
|
||||
* 64-bit integer. The previously computed integer to which the product is
|
||||
* added is located in the result ("res") area, and is assumed to be a
|
||||
* 576-bit (72-byte, nine doubleword) unsigned integer, stored in memory
|
||||
* in little-double-wordian order. This value normally will be the result
|
||||
* of a previously computed nine doubleword result. It is not necessary
|
||||
* to pad the multiplicand with an additional 64-bit zero doubleword.
|
||||
*
|
||||
* Multiplicand, multiplier, and addend ideally should be aligned at
|
||||
* 16-byte boundaries for best performance. The code will function
|
||||
* correctly for alignment at eight-byte boundaries which are not 16-byte
|
||||
* boundaries, but the execution may be slightly slower due to even/odd
|
||||
* bank conflicts on PA-RISC 8000 processors.
|
||||
*
|
||||
* This function is designed to accept the same calling sequence as Bill
|
||||
* Ackerman's "maxpy_little" function. The carry from the ninth doubleword
|
||||
* of the result is written to the tenth word of the result, as is done by
|
||||
* Bill Ackerman's function. The final carry also is returned as an
|
||||
* integer, which may be ignored. The function prototype may be either
|
||||
* of the following:
|
||||
*
|
||||
* void multacc512( int l, chunk* m, const chunk* a, chunk* res );
|
||||
* or
|
||||
* int multacc512( int l, chunk* m, const chunk* a, chunk* res );
|
||||
*
|
||||
* where: "l" originally denoted vector lengths. This parameter is
|
||||
* ignored. This function always assumes a multiplicand length of
|
||||
* 512 bits (eight doublewords), and addend and result lengths of
|
||||
* 576 bits (nine doublewords).
|
||||
*
|
||||
* "m" is a pointer to the doubleword multiplier, ideally aligned
|
||||
* on a 16-byte boundary.
|
||||
*
|
||||
* "a" is a pointer to the eight-doubleword multiplicand, stored
|
||||
* in little-double-wordian order, and ideally aligned on a 16-byte
|
||||
* boundary.
|
||||
*
|
||||
* "res" is a pointer to the nine doubleword addend, and to the
|
||||
* nine-doubleword product computed by this function. The result
|
||||
* also is stored in little-double-wordian order, and ideally is
|
||||
* aligned on a 16-byte boundary. It is expected that the alignment
|
||||
* of the "res" area may alternate between even/odd doubleword
|
||||
* boundaries for successive calls for 512-bit x 512-bit
|
||||
* multiplications.
|
||||
*
|
||||
* The code for this function has been scheduled to use the parallelism
|
||||
* of the PA-RISC 8000 series microprocessors as well as the author was
|
||||
* able. Comments and/or suggestions for improvement are welcomed.
|
||||
*
|
||||
* The code is "64-bit safe". This means it may be called in either
|
||||
* the 32ILP context or the 64LP context. All 64-bits of registers are
|
||||
* saved and restored.
|
||||
*
|
||||
* This code is self-contained. It requires no other header files in order
|
||||
* to compile and to be linkable on a PA-RISC 2.0 machine. Symbolic
|
||||
* definitions for registers and stack offsets are included within this
|
||||
* one source file.
|
||||
*
|
||||
* This is a leaf routine. As such, minimal use is made of the stack area.
|
||||
* Of the 192 bytes allocated, 64 bytes are used for saving/restoring eight
|
||||
* general registers, and 128 bytes are used to move intermediate products
|
||||
* from the floating-point registers to the general registers. Stack
|
||||
* protocols assure proper alignment of these areas.

; This performs a multiple-precision integer version of "daxpy",

; the least significant word of a number is stored at the lowest address.
|
||||
; "Big-wordian" means that the most significant word is at the lowest
|
||||
; address. Either way, the incoming address of the vector is that
|

; of the least significant word. That means that, for little-wordian

; How to use "maxpy_PA20_little" and "maxpy_PA20_big"
|
||||
;
|
||||
; The routine "maxpy_PA20_little" or "maxpy_PA20_big"
|
||||
; performs a 64-bit x any-size multiply, and adds the
|
||||
; result to an area of memory. That is, it performs
|
||||
; something like
|
||||
;
|
||||
; A B C D
|
||||
; * Z
|
||||
; __________
|
||||
; P Q R S T
|
||||
;
|
||||
; and then adds the "PQRST" vector into an area of memory,
|
||||
; handling all carries.
|
||||
;
|
||||
; Digression on nomenclature and endian-ness:
|
||||
;
|
||||
; Each of the capital letters in the above represents a 64-bit
|
||||
; quantity. That is, you could think of the discussion as
|
||||
; being in terms of radix-16-quintillion arithmetic. The data
|
||||
; type being manipulated is "unsigned long long int". This
|
||||
; requires the 64-bit extension of the HP-UX C compiler,
|
||||
; available at release 10. You need these compiler flags to
|
||||
; enable these extensions:
|
||||
;
|
||||
; -Aa +e +DA2.0 +DS2.0
|
||||
;
|
||||
; (The first specifies ANSI C, the second enables the
|
||||
; extensions, which are beyond ANSI C, and the third and
|
||||
; fourth tell the compiler to use whatever features of the
|
||||
; PA2.0 architecture it wishes, in order to made the code more
|
||||
; efficient. Since the presence of the assembly code will
|
||||
; make the program unable to run on anything less than PA2.0,
|
||||
; you might as well gain the performance enhancements in the C
|
||||
; code as well.)
|
||||
;
|
||||
; Questions of "endian-ness" often come up, usually in the
|
||||
; context of byte ordering in a word. These routines have a
|
||||
; similar issue, that could be called "wordian-ness".
|
||||
; Independent of byte ordering (PA is always big-endian), one
|
||||
; can make two choices when representing extremely large
|
||||
; numbers as arrays of 64-bit doublewords in memory.
|
||||
;
|
||||
; "Little-wordian" layout means that the least significant
|
||||
; word of a number is stored at the lowest address.

;
|

; When you compile the file, you must specify one or the other, with
|
||||
; a switch "-DLITTLE_WORDIAN" or "-DBIG_WORDIAN".
|
||||
;
|
||||
; Incidentally, you assemble this file as part of your
|
||||
; project with the same C compiler as the rest of the program.
|
||||
; My "makefile" for a superprecision arithmetic package has
|
||||
; the following stuff:
|
||||
;
|
||||
; # definitions:
|
||||
; CC = cc -Aa +e -z +DA2.0 +DS2.0 +w1
|
||||
; CFLAGS = +O3
|
||||
; LDFLAGS = -L /usr/lib -Wl,-aarchive
|
||||
;
|
||||
; # general build rule for ".s" files:
|
||||
; .s.o:
|
||||
; $(CC) $(CFLAGS) -c $< -DBIG_WORDIAN
|
||||
;
|
||||
; # Now any bind step that calls for pa20.o will assemble pa20.s
|
||||
;
|
||||
; End of digression, back to arithmetic:
|
||||
;
|
||||
; The way we multiply two huge numbers is, of course, to multiply
|
||||
; the "ABCD" vector by each of the "WXYZ" doublewords, adding
|
||||
; the result vectors with increasing offsets, the way we learned
|
||||
; in school, back before we all used calculators:
|
||||
;
|
||||
; A B C D
|
||||
; * W X Y Z
|
||||
; __________
|
||||
; P Q R S T
|
||||
; E F G H I
|
||||
; M N O P Q
|
||||
; + R S T U V
|
||||
; _______________
|
||||
; F I N A L S U M
|
||||
;
|
||||
; So we call maxpy_PA20_big (in my case; my package is
|
||||
; big-wordian) repeatedly, giving the W, X, Y, and Z arguments
|
||||
; in turn as the "scalar", and giving the "ABCD" vector each
|
||||
; time. We direct it to add its result into an area of memory
|
||||
; that we have cleared at the start. We skew the exact
|
||||
; location into that area with each call.
|
||||
;
|
||||
; The prototype for the function is
|
||||
;
|
||||
; extern void maxpy_PA20_big(
|
||||
; int length, /* Number of doublewords in the multiplicand vector. */
|
||||
; const long long int *scalaraddr, /* Address to fetch the scalar. */
|
||||
; const long long int *multiplicand, /* The multiplicand vector. */
|
||||
; long long int *result); /* Where to accumulate the result. */
|
||||
;
|
||||
; (You should place a copy of this prototype in an include file
|
||||
; or in your C file.)
|
||||
;
|
||||
; Now, IN ALL CASES, the given address for the multiplicand or
|
||||
; the result is that of the LEAST SIGNIFICANT DOUBLEWORD.
|
||||
; That word is, of course, the word at which the routine
|
||||
; starts processing. "maxpy_PA20_little" then increases the
|
||||
; addresses as it computes. "maxpy_PA20_big" decreases them.
|
||||
;
|
||||
; In our example above, "length" would be 4 in each case.
|
||||
; "multiplicand" would be the "ABCD" vector. Specifically,
|
||||
; the address of the element "D". "scalaraddr" would be the
|
||||
; address of "W", "X", "Y", or "Z" on the four calls that we
|
||||
; would make. (The order doesn't matter, of course.)
|
||||
; "result" would be the appropriate address in the result
|
||||
; area. When multiplying by "Z", that would be the least
|
||||
; significant word. When multiplying by "Y", it would be the
|
||||
; next higher word (8 bytes higher if little-wordian; 8 bytes
|
||||
; lower if big-wordian), and so on. The size of the result
|
||||
; area must be the the sum of the sizes of the multiplicand
|
||||
; and multiplier vectors, and must be initialized to zero
|
||||
; before we start.
|
||||
;
|
||||
; Whenever the routine adds its partial product into the result
|
||||
; vector, it follows carry chains as far as they need to go.
|
||||
;
|
||||
; Here is the super-precision multiply routine that I use for
|
||||
; my package. The package is big-wordian. I have taken out
|
||||
; handling of exponents (it's a floating point package):
|
||||
;
|
||||
; static void mul_PA20(
|
||||
; int size,
|
||||
; const long long int *arg1,
|
||||
; const long long int *arg2,
|
||||
; long long int *result)
|
||||
; {
|
||||
; int i;
|
||||
;
|
||||
; for (i=0 ; i<2*size ; i++) result[i] = 0ULL;
|
||||
;
|
||||

|
||||
; maxpy_PA20_big(size, &arg2[i], &arg1[size-1], &result[size+i]);
|
