Rapid prototype of a fast data encryption standard with integrity processing for cryptographic applications

In this paper we present the design of a chip for real-time cryptographic processing in industrial applications. The chip acts as a co-processor of a system for the automatic ciphering and data integrity processing: it implements the DES/MAC algorithm (Data Encryption Standard/Message Authentication Code) in the same silicon area with high speed performance. These research come within a process aiming at reaching an implementation onto specialised pipeline and parallel architecture from algorithm specification. The design has been performed in rapid prototype ACTEL Programmable Gate Array Device using an approach based on high level transformations on the VHDL specifications. This paper is in part of an European Program which aims to design a macro cell library for cryptographic applications.
