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...
Chosen-message simple power analysis (SPA) attacks were powerful against public-key cryptosystem based on modular exponentiation, due to the special results of modular square and modular multiplication for input pair X and - X. However, the characteristics can not be applied to public-key cryptosystems based on scalar multiplications. This paper proposes novel chosen-message side-channel analysis...
RFID tags have gradually become popular tools for identification of products. To ensure the secure information transaction of tags, a scheme of RFID system authentication protocol based on Elliptic Curve Cryptography (ECC) is proposed. However, hardware implementation of ECC processor for RFID tags is a challenge for the requirements of low-power consumption and low-cost chip resource. In the paper...
