Implementation of Cryptographic Algorithm Based on MicroBlaze

This Paper presents the proposal for implementation of SMS4 cryptographic algorithm. Its main purpose is to increase the performance, and to improve use flexibility of the State’s commercial cipher symmetric algorithm SMS4, SOC design method for embedded soft core based on Xilinx Company’s MicroBlaze is developed to design key extension and encryption/decryption operation of SMS4 algorithm into IP hardcore by means of hardware and connect SMS4 hardcore to PLB or OPB by interface module.
