Each cipher encrypts and decrypts data in blocks of 128 bits. When more than 128 bits are processed the method used is known as a mode of operation and there are different modes for different purposes such as ECB, CBC, OFB, CFB, CTR, and XTS. AES is a new generation cipher that supports key lengths a minimum of 128 and a maximum of 256 bits, each with a fixed block size of 128 bits. This encryption algorithm is secure enough for all modern needs.

The AES-XTS encryption IP core implements encryption/decryption for sector-based storage data. It uses the AES block cypher, 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. The longer key sizes use more rounds: AES-128 uses 10 rounds, AES-192 uses 12 rounds and AES-256 uses 14 rounds.

By IEEE Std 1619-2007, two cipherkeys in 256 bits are required in XTS mode. They are called tweakable key and encryption key, respectively.
