This highly configurable implementation of the XTS-AES algorithm for storage encryption implements the full NIST SP800-38E specification used in IEEE standard 1619-2007. AES XTS is based on a pipelined implementation of AES to provide throughput to match multi-gigabit storage connection schemes such as USB 3.0 and SATA 3.0.

The AES-XTS core is based on our NIST validated AES-G3 implementation and is supplied as a complete package of VHDL or Verilog source code. The number of pipelined AES encryptors is configurable allowing a flexible tradeoff of area against performance.
