Dynamic password technology is widely utilized for identity authentication, which depends on using hash functions, such as SM3. And SM3 hash algorithm is based on the mixing of different group operations, such as XOR and addition modulo 232. In this paper, we present two original first-order differential power analysis attacks on dynamic password token based on SM3 algorithm. The two proposed DPA...
He HMAC algorithm involves a hash function with a secret key. And SM3 is the only standard hash algorithm of China. HMAC-SM3 algorithm is based on the mixing of different algebraic operations, such as XOR and addition modulo 232, thus the classical side-channel attacks on it are mainly against these basic group operations and need to exploit multiple leakage models. Therefore, the attack procedures...
