CLP-19: Ultra-high Throughput DES/3DES Core - 1.3 Gbps

One of the most popular ciphers in use today is 3DES. 3DES is a variant of the Digital Encryption Standard (DES) cipher. The CLP-19 is an improved design through the implementation of timing and state machine optimizations to achieve throughput 30% greater than the CLP-08 core. The CLP-19 DES/3DES core combines both algorithms into a single block which is selectable via a mode bit.

Key Features:

• Throughput over 1300 Mbps in 3DES mode
• Electronic Codebook (ECB) or Cipher Block Chaining (CBC) modes
• Implemented against the FIPS 46-3 standard
• Input memory block is configurable with shadow memory to allow input of next block while 3DES/DES operation in progress
• Automatic generation of key context from key data
• Key memory accessible through memory interface
• Key memory sized to support up to 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
