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; u128 V; Htable[0].hi = 0; Htable[0].lo = 0; V.hi = H[0]; V.lo = H[1]; for (Htable[128]=V, i=64; i>0; i>>=1) { REDUCE1BIT(V); Htable[i] = V; } for (i=2; i<256; i<<=1) { u128 *Hi = Htable+i, H0 = *Hi; for (j=1; j>8); Z.hi = (Z.hi>>8); if (sizeof(size_t)==8) Z.hi ^= rem_8bit[rem]; else Z.hi ^= (u64)rem_8bit[rem]<<32; } if (is_endian.little) { #ifdef BSWAP8 Xi[0] = BSWAP8(Z.hi); Xi[1] = BSWAP8(Z.lo); #else u8 *p = (u8 *)Xi; u32 v; v = (u32)(Z.hi>>32); PUTU32(p,v); v = (u32)(Z.hi); PUTU32(p+4,v); v = (u32)(Z.lo>>32); PUTU32(p+8,v); v = (u32)(Z.lo); PUTU32(p+12,v); #endif } else { Xi[0] = Z.hi; Xi[1] = Z.lo; } } #define GCM_MUL(ctx,Xi) gcm_gmult_8bit(ctx->Xi.u,ctx->Htable) #elif TABLE_BITS==4 static void gcm_init_4bit(u128 Htable[16], u64 H[2]) { u128 V; #if defined(OPENSSL_SMALL_FOOTPRINT) int i; #endif Htable[0].hi = 0; Htable[0].lo = 0; V.hi = H[0]; V.lo = H[1]; #if defined(OPENSSL_SMALL_FOOTPRINT) for (Htable[8]=V, i=4; i>0; i>>=1) { REDUCE1BIT(V); Htable[i] = V; } for (i=2; i<16; i<<=1) { u128 *Hi = Htable+i; int j; for (V=*Hi, j=1; j>32; Htable[j].lo = V.hi<<32|V.hi>>32; } } #endif } #ifndef GHASH_ASM __fips_constseg static const size_t rem_4bit[16] = { PACK(0x0000), PACK(0x1C20), PACK(0x3840), PACK(0x2460), PACK(0x7080), PACK(0x6CA0), PACK(0x48C0), PACK(0x54E0), PACK(0xE100), PACK(0xFD20), PACK(0xD940), PACK(0xC560), PACK(0x9180), PACK(0x8DA0), PACK(0xA9C0), PACK(0xB5E0) }; static void gcm_gmult_4bit(u64 Xi[2], const u128 Htable[16]) { u128 Z; int cnt = 15; size_t rem, nlo, nhi; const union { long one; char little; } is_endian = {1}; nlo = ((const u8 *)Xi)[15]; nhi = nlo>>4; nlo &= 0xf; Z.hi = Htable[nlo].hi; Z.lo = Htable[nlo].lo; while (1) { rem = (size_t)Z.lo&0xf; Z.lo = (Z.hi<<60)|(Z.lo>>4); Z.hi = (Z.hi>>4); if (sizeof(size_t)==8) Z.hi ^= rem_4bit[rem]; else Z.hi ^= (u64)rem_4bit[rem]<<32; Z.hi ^= Htable[nhi].hi; Z.lo ^= Htable[nhi].lo; if (--cnt<0) break; nlo = ((const u8 *)Xi)[cnt]; nhi = nlo>>4; nlo &= 0xf; rem = (size_t)Z.lo&0xf; Z.lo = (Z.hi<<60)|(Z.lo>>4); Z.hi = (Z.hi>>4); if (sizeof(size_t)==8) Z.hi ^= rem_4bit[rem]; else Z.hi ^= (u64)rem_4bit[rem]<<32; Z.hi ^= Htable[nlo].hi; Z.lo ^= Htable[nlo].lo; } if (is_endian.little) { #ifdef BSWAP8 Xi[0] = BSWAP8(Z.hi); Xi[1] = BSWAP8(Z.lo); #else u8 *p = (u8 *)Xi; u32 v; v = (u32)(Z.hi>>32); PUTU32(p,v); v = (u32)(Z.hi); PUTU32(p+4,v); v = (u32)(Z.lo>>32); PUTU32(p+8,v); v = (u32)(Z.lo); PUTU32(p+12,v); #endif } else { Xi[0] = Z.hi; Xi[1] = Z.lo; } } #if !defined(OPENSSL_SMALL_FOOTPRINT) /* * Streamed gcm_mult_4bit, see CRYPTO_gcm128_[en|de]crypt for * details...
