Abstract

Side channel analysis has seriously threatened the application security of cryptographic algorithms. In order to improve the ability of SM4 algorithm to resist side channel analysis, this paper proposed a threshold masking scheme for SM4 algorithm. Firstly, it decomposed the S-box of SM4 algorithm. Then this paper designed the threshold masking method based on two sharing pattern for SM4. According to the method, the schema split the S-box input into two shares by using random number, and rebuilt the circuit by composite field operation and the S-box threshold masking, and reduced the hardware cost by reusing S-boxes. After the linear layer operation, the schema carried out unmasked operation by XOR the two output results. The simulation results and security test results of FPGA implementation for SM4 threshold masking schema show that the masking scheme can effectively resist CPA attack, and its implementation area is lower.
