This application note describes the implementation of high-performance Data Encryption Standard (DES) and Triple DES encryptor/decryptor in Virtex™-II and Virtex-E devices. This implementation operates at 15 Gb/s, making it the fastest encryptor/decryptor available today, surpassing the previous record holder, a custom ASIC (Sandia). This design fits into an XC2V1000 or an XCV400E. Three copies of the DES engine can be combined to triple the bandwidth to 45 Gb/s or to permit Triple-DES encryption at the same data rate, but with additional latency.
