| 12 # This is AESNI-CBC+SHA1 "stitch" implementation. The idea, as spelled | |
| 13 # in http://download.intel.com/design/intarch/papers/323686.pdf, is | |
| 14 # that since AESNI-CBC encrypt exhibit *very* low instruction-level | |
| 15 # parallelism, interleaving it with another algorithm would allow to | |
| 16 # utilize processor resources better and achieve better performance. | |
| 17 # SHA1 instruction sequences(*) are taken from sha1-x86_64.pl and | |
| 18 # AESNI code is weaved into it. Below are performance numbers in | |
| 19 # cycles per processed byte, less is better, for standalone AESNI-CBC | |
| 20 # encrypt, sum of the latter and standalone SHA1, and "stitched" | |
| 21 # subroutine: | |
| 22 # | |
| 23 # AES-128-CBC +SHA1 stitch gain | |
| 24 # Westmere 3.77[+5.6] 9.37 6.65 +41% | |
| 25 # Sandy Bridge 5.05[+5.2(6.3)] 10.25(11.35) 6.16(7.08) +67%(+60%) | |
| 26 # | |
| 27 # AES-192-CBC | |
| 28 # Westmere 4.51 10.11 6.97 +45% | |
| 29 # Sandy Bridge 6.05 11.25(12.35) 6.34(7.27) +77%(+70%) | |
| 30 # | |
| 31 # AES-256-CBC | |
| 32 # Westmere 5.25 10.85 7.25 +50% | |
| 33 # Sandy Bridge 7.05 12.25(13.35) 7.06(7.70) +74%(+73%) | |
| 34 # | |
| 35 # (*) There are two code paths: SSSE3 and AVX. See sha1-568.pl for | |
| 36 # background information. Above numbers in parentheses are SSSE3 | |
| 37 # results collected on AVX-capable CPU, i.e. apply on OSes that | |
| 38 # don't support AVX. | |
| 39 # | |
| 40 # Needless to mention that it makes no sense to implement "stitched" | |
| 41 # *decrypt* subroutine. Because *both* AESNI-CBC decrypt and SHA1 | |
| 42 # fully utilize parallelism, so stitching would not give any gain | |
| 43 # anyway. Well, there might be some, e.g. because of better cache | |
| 44 # locality... For reference, here are performance results for | |
| 45 # standalone AESNI-CBC decrypt: | |
| 46 # | |
| 47 # AES-128-CBC AES-192-CBC AES-256-CBC | |
| 48 # Westmere 1.31 1.55 1.80 | |
| 49 # Sandy Bridge 0.93 1.06 1.22 | |
