CLP-08: High Throughput DES/3DES Core
One of the most popular ciphers in use today is 3DES. 3DES is a variant of the Digital Encryption Standard (DES) cipher improved through the implementation of additional cipher rounds and key mixing. The CLP-08 DES/3DES core combines both algorithms into a single block which is selectable via a mode bit. This security core is silicon-proven and offers 3DES performance beyond 1 Gbps.
