- # September 2011.
- #
- # Started as transliteration to "perlasm" the original code has
- # undergone following changes:
- #
- # - code was made position-independent;
- # - rounds were folded into a loop resulting in >5x size reduction
- # from 12.5KB to 2.2KB;
- # - above was possibile thanks to mixcolumns() modification that
- # allowed to feed its output back to aesenc[last], this was
- # achieved at cost of two additional inter-registers moves;
- # - some instruction reordering and interleaving;
- # - this module doesn't implement key setup subroutine, instead it
- # relies on conversion of "conventional" key schedule as returned
- # by AES_set_encrypt_key (see discussion below);
- # - first and last round keys are treated differently, which allowed
- # to skip one shiftrows(), reduce bit-sliced key schedule and
- # speed-up conversion by 22%;
- # - support for 192- and 256-bit keys was added;
- #
- # Resulting performance in CPU cycles spent to encrypt one byte out
- # of 4096-byte buffer with 128-bit key is:
- #
- # Emilia's this(*) difference
- #
- # Core 2 9.30 8.69 +7%
- # Nehalem(**) 7.63 6.88 +11%
- # Atom 17.1 16.4 +4%
- # Silvermont - 12.9
- # Goldmont - 8.85
- #
- # (*) Comparison is not completely fair, because "this" is ECB,
- # i.e. no extra processing such as counter values calculation
- # and xor-ing input as in Emilia's CTR implementation is
- # performed. However, the CTR calculations stand for not more
- # than 1% of total time, so comparison is *rather* fair.
- #
- # (**) Results were collected on Westmere, which is considered to
- # be equivalent to Nehalem for this code.
- #
- # As for key schedule conversion subroutine. Interface to OpenSSL
- # relies on per-invocation on-the-fly conversion. This naturally
- # has impact on performance, especially for short inputs. Conversion
- # time in CPU cycles and its ratio to CPU cycles spent in 8x block
- # function is:
- #
- # conversion conversion/8x block
- # Core 2 240 0.22
- # Nehalem 180 0.20
- # Atom 430 0.20
- #
- # The ratio values mean that 128-byte blocks will be processed
- # 16-18% slower, 256-byte blocks - 9-10%, 384-byte blocks - 6-7%,
- # etc. Then keep in mind that input sizes not divisible by 128 are
- # *effectively* slower, especially shortest ones, e.g. consecutive
- # 144-byte blocks are processed 44% slower than one would expect,
- # 272 - 29%, 400 - 22%, etc. Yet, despite all these "shortcomings"
- # it's still faster than ["hyper-threading-safe" code path in]
- # aes-x86_64.pl on all lengths above 64 bytes...
- #
- # October 2011.
- #
- # Add decryption procedure. Performance in CPU cycles spent to decrypt
- # one byte out of 4096-byte buffer with 128-bit key is:
- #
- # Core 2 9.98
- # Nehalem 7.80
- # Atom 17.9
- # Silvermont 14.0
- # Goldmont 10.2
- #
- # November 2011.
- #
- # Add bsaes_xts_[en|de]crypt. Less-than-80-bytes-block performance is
- # suboptimal, but XTS is meant to be used with larger blocks...
