The silicon-proven DesignWare® Pipelined AES-XTS core is a highly integrated security engine targeted at rotating and solid state disk applications. Developed by industry experts through a structured and rigorous development and verification program, the core supports the tweakable narrow-block AES-XTS as specified in the IEEE Std 1619-2007 standard. XTS is defined as the XEX-based tweaked codebook mode (TCB) with ciphertext stealing (CTS) algorithm.
The DesignWare Pipelined AES-XTS Core allows designers of applications including flash or solid state disk drives, disk/storage and RAID encryption, Serial Attached SCSI (G1 through G3), and Fibre Channel (all currently defined traffic rates) to select a configuration that is optimized for their required performance and gate count to reduce design risk and speed time to market.
