A Novel Masking Scheme for SM3 Based MAC

摘要：

　　The Chinese hash algorithm SM3 is verified to be secure enough, but improper hardware implementation may lead to leakage.A masking scheme for SM3 algorithm is proposed to ensure the security of SM3 based Message Authentication Code (MAC).Our scheme was implemented in hardware,which utilizes hardware oriented secure conversion techniques between boolean and arithmetic masking.Security evaluation based on SAKURA-G FPGA board has been done with 2000 power traces from 2000 random plaintexts with random plaintext masks and random key masks.It has been verified that the masked SM3 hardware implementation shows no intermediate value leakage as expected.Our masked SM3 hardware can resist first-order correlation power attack (CPA) and collision correlation attack.Furthermore we are keeping on research of side-channel attack and defense of HMAC-SM3.
