Scheme Design of Resisting Differential Power Analysis Attack for DES in Cryptographic Chip
摘要
Abstract
In order to resist power analysis attacks aiming to the data encryption standard algorithm in cryptographic chips,a scheme design of middle value masking for data encryption standard algorithm based on complementary circuit is proposed according to the principle and the resistance countermeasures of power analysis attacks aiming to data encryption standard algorithm. The scheme mainly carries out the complementary output by using the double ciruit in order to ensure keeping the power consumption constant of register in roll-in-over and to decrease the difference of power consumption farthest. Performance analysis results demonstrate that the scheme can resist differential power analysis attacks and make easy to be implemented,and can be applied in the circuit design of cryptographic chips directly.关键词
