It uses the AES block cipher, in compliance with the NIST Advanced Encryption Standard, as a subroutine. The core processes 128 bits per cycle, and is programmable for 128- and 256-bit key lengths. Two architectural versions are available to suit system size and throughput requirements. The High Throughput XTS-X is more compact and can process 128 bits/cycle independent of the key size. The Higher Throughput XTS-X2 can process 256 bits/cycle independent of the key size. Both versions have a 128-bit data path. XTS (XEX-based Tweaked Codebook Mode with Ciphertext Stealing) is a mode of AES that has been specifically designed to encrypt fixed-size data where a possible threat has access to the stored data.
