Abstract

The combination of traditional microprocessors and Field Programmable Gate Arrays (FPGAs) is developing as a future platform for intensive computational computing, combining the best aspects of traditional microprocessor front-end development with the reconfigurability of FPGAs for computation-intensive problems. Several prototype PC-FPGA machines have demonstrated significant speedups compared to standalone PC workstations for computationally intensive problems. Cryptographic applications are a clear candidate for this type of platform, due to their computational intensity and long operand lengths. In this paper, we demonstrate an efficient implementation of IDEA encryption, using two of the leading reconfigurable computers available, SRC Computers’ SRC-6E and Star Bridge Systems’ HC-36. We compare the hardware architecture and programming model of these reconfigurable computers, and the implementation of a common IDEA encryption architecture in both platforms. Detailed analyses of FPGA resource utilization for both systems, data transfer and reconfiguration overheads for the SRC system, and a comparison between SRC and a public domain software implementation are given in the paper.
