| 14 # | |
| 15 # September 2011. | |
| 16 # | |
| 17 # Started as transliteration to "perlasm" the original code has | |
| 18 # undergone following changes: | |
| 19 # | |
| 20 # - code was made position-independent; | |
| 21 # - rounds were folded into a loop resulting in >5x size reduction | |
| 22 # from 12.5KB to 2.2KB; | |
| 23 # - above was possibile thanks to mixcolumns() modification that | |
| 24 # allowed to feed its output back to aesenc[last], this was | |
| 25 # achieved at cost of two additional inter-registers moves; | |
| 26 # - some instruction reordering and interleaving; | |
| 27 # - this module doesn't implement key setup subroutine, instead it | |
| 28 # relies on conversion of "conventional" key schedule as returned | |
| 29 # by AES_set_encrypt_key (see discussion below); | |
| 30 # - first and last round keys are treated differently, which allowed | |
| 31 # to skip one shiftrows(), reduce bit-sliced key schedule and | |
| 32 # speed-up conversion by 22%; | |
| 33 # - support for 192- and 256-bit keys was added; | |
| 34 # | |
| 35 # Resulting performance in CPU cycles spent to encrypt one byte out | |
| 36 # of 4096-byte buffer with 128-bit key is: | |
| 37 # | |
| 38 # Emilia's this(*) difference | |
| 39 # | |
| 40 # Core 2 9.30 8.69 +7% | |
| 41 # Nehalem(**) 7.63 6.98 +9% | |
| 42 # Atom 17.1 17.4 -2%(***) | |
| 43 # | |
| 44 # (*) Comparison is not completely fair, because "this" is ECB, | |
| 45 # i.e. no extra processing such as counter values calculation | |
| 46 # and xor-ing input as in Emilia's CTR implementation is | |
| 47 # performed. However, the CTR calculations stand for not more | |
| 48 # than 1% of total time, so comparison is *rather* fair. | |
| 49 # | |
| 50 # (**) Results were collected on Westmere, which is considered to | |
| 51 # be equivalent to Nehalem for this code. | |
| 52 # | |
| 53 # (***) Slowdown on Atom is rather strange per se, because original | |
| 54 # implementation has a number of 9+-bytes instructions, which | |
| 55 # are bad for Atom front-end, and which I eliminated completely. | |
| 56 # In attempt to address deterioration sbox() was tested in FP | |
| 57 # SIMD "domain" (movaps instead of movdqa, xorps instead of | |
| 58 # pxor, etc.). While it resulted in nominal 4% improvement on | |
| 59 # Atom, it hurted Westmere by more than 2x factor. | |
| 60 # | |
| 61 # As for key schedule conversion subroutine. Interface to OpenSSL | |
| 62 # relies on per-invocation on-the-fly conversion. This naturally | |
| 63 # has impact on performance, especially for short inputs. Conversion | |
| 64 # time in CPU cycles and its ratio to CPU cycles spent in 8x block | |
| 65 # function is: | |
| 66 # | |
| 67 # conversion conversion/8x block | |
| 68 # Core 2 240 0.22 | |
| 69 # Nehalem 180 0.20 | |
| 70 # Atom 430 0.19 | |
| 71 # | |
| 72 # The ratio values mean that 128-byte blocks will be processed | |
| 73 # 16-18% slower, 256-byte blocks - 9-10%, 384-byte blocks - 6-7%, | |
| 74 # etc. Then keep in mind that input sizes not divisible by 128 are | |
| 75 # *effectively* slower, especially shortest ones, e.g. consecutive | |
| 76 # 144-byte blocks are processed 44% slower than one would expect, | |
| 77 # 272 - 29%, 400 - 22%, etc. Yet, despite all these "shortcomings" | |
| 78 # it's still faster than ["hyper-threading-safe" code path in] | |
| 79 # aes-x86_64.pl on all lengths above 64 bytes... | |
| 80 # | |
| 81 # October 2011. | |
| 82 # | |
| 83 # Add decryption procedure. Performance in CPU cycles spent to decrypt | |
| 84 # one byte out of 4096-byte buffer with 128-bit key is: | |
| 85 # | |
| 86 # Core 2 11.0 | |
| 87 # Nehalem 9.16 | |
| 88 # Atom 20.9 | |
| 89 # | |
| 90 # November 2011. | |
| 91 # | |
| 92 # Add bsaes_xts_[en|de]crypt. Less-than-80-bytes-block performance is | |
| 93 # suboptimal, but XTS is meant to be used with larger blocks... | |
