In other words OpenSSL does not cover + * whole spectrum of possible table driven implementations. Why? In + * non-"Shoup's" case memory access pattern is segmented in such manner, + * that it's trivial to see that cache timing information can reveal + * fair portion of intermediate hash value. Given that ciphertext is + * always available to attacker, it's possible for him to attempt to + * deduce secret parameter H and if successful, tamper with messages + * [which is nothing but trivial in CTR mode]. In "Shoup's" case it's + * not as trivial, but there is no reason to believe that it's resistant + * to cache-timing attack. And the thing about "8-bit" implementation is + * that it consumes 16 (sixteen) times more memory, 4KB per individual + * key + 1KB shared. Well, on pros side it should be twice as fast as + * "4-bit" version. And for gcc-generated x86[_64] code, "8-bit" version + * was observed to run ~75% faster, closer to 100% for commercial + * compilers... Yet "4-bit" procedure is preferred, because it's + * believed to provide better security-performance balance and adequate + * all-round performance. "All-round" refers to things like: + * + * - shorter setup time effectively improves overall timing for + *   handling short messages; + * - larger table allocation can become unbearable because of VM + *   subsystem penalties (for example on Windows large enough free + *   results in VM working set trimming, meaning that consequent + *   malloc would immediately incur working set expansion); + * - larger table has larger cache footprint, which can affect + *   performance of other code paths (not necessarily even from same + *   thread in Hyper-Threading world); + * + * Value of 1 is not appropriate for performance reasons. + */ +#if     TABLE_BITS==8 + +static void gcm_init_8bit(u128 Htable[256], u64 H[2]) +{ +    int i, j;
