Realization of SMS4 Algorithm Based on Share Memory of the Heterogeneous Multi-Core Password Chip System

Abstract

In order to meet the rapid demand of the modern cryptographic communication, heterogeneous multi-core password system architecture is set up based on shared memory in Xilinx XUP Virtex-II Pro chip in this paper. Under this architecture, the encryption and decryption of the SMS4 algorithm is realized fastly. Make a contrast with the homogeneous multi-core password system and the heterogeneous one-core password system’s performance in the execution time, throughput and resource utilization of the SMS4 algorithm.The experimental results show that the heterogeneous multi-core password system which based on shared memory has better performance.
