923 data dependent latencies as much as possible without affecting
924 performance too much. It is intended for use by the generic CCM
925 and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
926 solely on encryption (although decryption is supported as well, but
927 with a more dramatic performance hit)
929 Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
930 8 for decryption), this implementation only uses just two S-boxes of
931 256 bytes each, and attempts to eliminate data dependent latencies by
