 538           CPUs without dedicated crypto instructions.  It encrypts
 539           each sector using the XChaCha12 stream cipher, two passes of
 540           an ε-almost-∆-universal hash function, and an invocation of
 541           the AES-256 block cipher on a single 16-byte block.  On CPUs
 542           without AES instructions, Adiantum is much faster than
 543           AES-XTS.
 544
 545           Adiantum's security is provably reducible to that of its
 546           underlying stream and block ciphers, subject to a security
 547           bound.  Unlike XTS, Adiantum is a true wide-block encryption
 548           mode, so it actually provides an even stronger notion of
 549           security than XTS, subject to the security bound.

1067           This is a generic implementation of AES that attempts to eliminate
1068           data dependent latencies as much as possible without affecting
1069           performance too much. It is intended for use by the generic CCM
1070           and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
1071           solely on encryption (although decryption is supported as well, but

1074           Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
1075           8 for decryption), this implementation only uses just two S-boxes of
1076           256 bytes each, and attempts to eliminate data dependent latencies by
1077           prefetching the entire table into the cache at the start of each
1078           block. Interrupts are also disabled to avoid races where cachelines
