Triple DES Coprocessor

​​​The Triple DES Coprocessor is a Data Encryption Standard (FIPS 46-3) peripheral computing DES or TDES encryption and decryption through a highly-optimized secure architecture. Based on 2.5 kgates, the Triple DES Coprocessor computes DES and TDES in 16 and 48 cycles respectively.

Key Features

​FIP 46-3 compliant
Three versions available
Small gate count
Protected register access
Silicon proven​

Features

  • DES and TDES decryption and encryption
