0.12 -- Christophe Devine contributed MIPS asm w00t
|
|
++ quick release to get the MIPS code out there
|
|
|

|
0.11 -- re-org'ed the source tree, it's cooler now
|
|
-- cleaned up mul/sqr so there is only one file per unit, should help building with older compilers and/or on slower boxes
|
|
-- [CRI] optimized fp_read_unsigned_bin
|
|
-- fixed -0 ... again ... I now have less hair on my head.
|
|
-- [CRI] renamed bn_reverse() -> fp_reverse()
|

0.10 -- Unrolled Montgomery for 1..16 digits with TFM_SMALL_MONT_SET between 10% and 25% speedup depending on size.
|
|
-- fixed fp_sqr_comba.c so it builds in ISO C mode [Andreas Lange]
|
|
-- cisc@broadpark.no pointed out fp_radix_size() had a few typos that affected correctness. Fixed.
|
|
-- Added support for ECC performance, e.g. define "-DTFM_ALREADY_SET -DTFM_ECC192" and it will disable
|
|
all of the unrolled code EXCEPT what is required for ECC P-192. It autodetects 32/64-bit platforms too. It's super neato.
|
|
Support for 192, 224, 256, 384 and 521 bit curves through the defines [see tfm.h]
|
|
-- AVR32 support added, define TFM_AVR32 to enable
|
|
|
|

|
0.09 -- Bruce Guenter suggested I use --tag=CC for libtool builds where the compiler may think it's C++.
|
|
-- Added support for k=1 in exptmod for RSA exponents. Makes it more competitive with other libraries
|
|
-- added cutoffs to the comba32 sqr/mul code to better handle 640, 786 and 896 bit operands (e.g. for RSA-1280, RSA-1536 and RSA-1792), really no effect
|
|
for 64-bit boxes as these represent 1280, 1536 and 1792 bit operands (not likely to be invoked).
|
|
-- Removed karatsuba from the mul/sqr since they're not useful and slow.
|
|
-- added 20, 24 and 28 digit multipliers for oddsized RSA support. You can easily disable them by uncommenting the TFM_SQRXX and TFM_MULXX lines in
|
|
tfm.h to save space. Now GMP and TFM are roughly the same speed on the Pentium-M for RSA with LTC.
|
|
-- unrolled SSE2 code and optimize for platforms with load/store pipes (e.g. can store and load in a cycle). Got 4% or so boost on my Dothan laptop (marginal improvement on a P4 Prescott)
|
|
|
|
Jan 26th, 2006
|
|
0.08 -- Fixed a bug in the generic mult/sqr where we overflowed by one digit
|
|
|
|
November 18th, 2005
|
|
0.07 -- Fixes to fp_mul and fp_sqr to clean up the handling of the defines, fix to tfm.h to also clear up the prototypes.
|
|
-- Updates to build and run on a IBM PPC 405 [using GCC 3.4.4]
|
|
-- Made the "make" command renamable in the build system
|
|
|
|
October 31st, 2005
|
|
0.06 -- fixed fp_mul() and fp_sqr() to trim digits when overflows would occur. Produces numerically inprecise results
|
|
(e.g. the lower FP_SIZE digits) but shouldn't segfault at least ;-)
|
|
-- Updated the combas so you can turn on and off specific unrolled loops at build time
|
|
-- Michael Heyman reported a bug in s_fp_sub() that was pretty substantial and a bug in fp_montgomery_calc_normalization(). Fixed.
|
|
|
|
August 1st, 2005
|
|
0.05 -- Quick fix to the fp_invmod.c code to let it handle even moduli [required for LTC]
|
|
-- Added makefile.shared to make shared objects [required for LTC]
|
|
-- Improved makefiles to make them way more configurable
|
|
-- Added timing resistant fp_exptmod() enabled with TFM_TIMING_RESISTANT
|
|
|
|
July 23rd, 2005
|
|
0.04 -- Fixed bugs in the SSE2 squaring code
|
|
-- Rewrote the multipliers to be optimized for small inputs
|
|
-- Nelson Bolyard of the NSS crew submitted [among other things] new faster Montgomery reduction
|
|
code. It brings the performance for small numbers on the AMD64 and all numbers on the P4
|
|
to a new level. Thanks!
|
|
-- Added missing ARM support for fp_montgomery_reduce.c that the NSS folk left off, Officially
|
|
the ARM code is for v4 and above WITH the "M" multiplier support (e.g. umlal instruction)
|
|
-- Added PPC32 support, define TFM_PPC32 to enable it, I used the "PowerPC 6xx" instruction
|
|
databook for reference. Does not require altivec. Should be fairly portable to the other
|
|
32-bit PPCs provided they have mullw and mulhwu instructions.
|
|
[Note: porting the macros to PPC64 should be trivial, anyone with a shell to lend... email me!]
|
|
-- Rewrote the config a bit in tfm.h so you can better choose which set of "oh my god that's huge" code to
|
|
enable for your task. "generic" functions are ALWAYS included which are smaller but will cover the
|
|
gaps in the coverage for ya.
|
|
-- The PPC32 code has been verified to function on a Darwin box running GCC 2.95.2
|
|
[Thanks to the folk at PeerSec for lending me a shell to use]
|
|
-- Fixed a bug in fp_exptmod() where if the exponent was negative AND the destination the output
|
|
would have the sign set to FP_NEG.
|
|
|
|
March 1st, 2005
|
|
0.03 -- Optimized squaring
|
|
-- Applied new license header to all files (still PD)
|
|
|
|
September 18th, 2004
|
|
0.02 -- Added TFM_LARGE to turn on/off 16x combas to save even more space.
|
|
This also helps prevent killing the cache on smaller cpus.
|
|
-- Cast memset to void in fp_init() to catch people who misuse the function (e.g. expect return)
|
|
Thanks to Johan Lindh
|
|
-- Cleaned up x86-64 support [faster montgomery reductions]
|
|
-- Autodetects x86-32 and x86-64 and enables it's asm now
|
|
-- Made test demo build cleaner in multilib platforms [e.g. mixed 32/64 bits]
|
|
-- Fix to fp_mod to ensure that remainder is of the same sign as the modulus.
|
|
-- Fixed bug in fp_montgomery_calc_normalization for single digit moduli
|
|
-- cleaned up ISO C macros in comba/mont to avoid branches [works best with GCC 3.4.x branch]
|
|
-- Added more testing to tfm.h to help detect misconfigured builds
|
|
-- Added TFM_NO_ASM which forces ASM off [even if it was autodetected].
|
|
-- Added fp_radix_size() to API
|
|
-- Cleaned up demo/test.c to build with far fewer warnings (mostly %d => %lu fixes)
|
|
-- fp_exptmod() now supports negative exponent and base>modulus cases
|
|
-- Added fp_ident() which gives a string showing how TFM was configured. Useful for debuging...
|
|
-- fix gen.pl script so it includes the whole source tree now
|
