| # 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% |
| # |
| # (*) 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 |
| # |
| # 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... |
