Summary

In this paper we introduce CCproc, a symmetric-key cryptographic (co)processor with a custom instruction set optimized for cryptographic applications. We study ten popular crypto algorithms, and provide custom solutions for them, while we also offer general support for future encryption algorithms. We design a custom but simple datapath able to execute the proposed instruction set and analyze its performance, proving to be competitive with other general purpose (but not custom) approaches, while having very small implementation cost.
