CLP-08: High Throughput DES/3DES Core - 1+ Gbps

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 core is an enhanced version of the silicon-proven CLP-02 core and offers 3DES performance beyond 1 Gbps.

Key Features:

• Throughput over 1000 Mbps in 3DES mode
• Electronic Codebook (ECB) or Cipher Block Chaining (CBC) modes
• Build options to optimize gate count for the target throughput
• Implemented against the FIPS 46-3 standard
• Input memory block is configurable with shadow memory to allow input of next block while DES operation in progress
• Automatic generation of key context from key data
• Key memory accessible through memory interface
• Key memory sized to support 3-Key 3DES modes
• Shared memory interface or optional FIFO interfaces available
• Test bench provided

Applications:

• IPSec designs in routers, switches, firewalls and network appliances
• Storage - SAN/NAS applications
• Military communications systems
