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;
