| ## Constant-time SSSE3 AES core implementation. |

| ## By Mike Hamburg (Stanford University), 2009 |
| ## Public domain. |

| # September 2011. |
| # |
| # Interface to OpenSSL as "almost" drop-in replacement for |
| # aes-x86_64.pl. "Almost" refers to the fact that AES_cbc_encrypt |
| # doesn't handle partial vectors (doesn't have to if called from |
| # EVP only). "Drop-in" implies that this module doesn't share key |
| # schedule structure with the original nor does it make assumption |
| # about its alignment... |
| # |
| # Performance summary. aes-x86_64.pl column lists large-block CBC |
| # encrypt/decrypt/with-hyper-threading-off(*) results in cycles per |
| # byte processed with 128-bit key, and vpaes-x86_64.pl column - |
| # [also large-block CBC] encrypt/decrypt. |
| # |
| # aes-x86_64.pl vpaes-x86_64.pl |
| # |
| # Core 2(**) 29.6/41.1/14.3 21.9/25.2(***) |
| # Nehalem 29.6/40.3/14.6 10.0/11.8 |
| # Atom 57.3/74.2/32.1 60.9/77.2(***) |
| # Silvermont 52.7/64.0/19.5 48.8/60.8(***) |
| # |
| # (*) "Hyper-threading" in the context refers rather to cache shared |
| # among multiple cores, than to specifically Intel HTT. As vast |
| # majority of contemporary cores share cache, slower code path |
| # is common place. In other words "with-hyper-threading-off" |
| # results are presented mostly for reference purposes. |
| # |
| # (**) "Core 2" refers to initial 65nm design, a.k.a. Conroe. |
| # |
| # (***) Less impressive improvement on Core 2 and Atom is due to slow |
| # pshufb, yet it's respectable +36%/62% improvement on Core 2 |
| # (as implied, over "hyper-threading-safe" code path). |
