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
