In this paper, the authors present CCProc, a flexible cryptography co-processor for symmetric-key algorithms. Based on an extensive analysis of many symmetric-key ciphers, including the five AES finalists, they designed an instruction set architecture tailored to symmetric-key ciphers and built a hardware processor prototype by using the VHDL language. The design was mapped on FPGAs and ASIC. Results show a small-area design, while also supporting many ciphers. Besides flexibility, a 4-core FPGA design can achieve up to 615 Mbits/sec at 95 MHz for Rijndael.
