Design and implementation of a new cryptographic system for multimedia transmission

In this paper, we propose a new cryptographic system based on the Shannon product theory. Analysis shows it has high security. Regarding real-time applications, a five-stage pipeline architecture has been designed, implemented, and verified based on a UMC 0.18 /spl mu/m CMOS technology. The simulation result shows that the proposed design achieves a throughput rates of the encryption part up to 2.79 Gbps at a silicon area cost of of 225360 /spl mu/m/sup 2/ and a power consumption of 16.93 mW. A comparison shows that the performance of the proposed design is much better than the existing designs.
