摘要:Aiming to protect cryptographic circuits against physical attacks, researchers have proposed a variety of mature and effective countermeasures. However, most of these defensive technologies are used for specific and single attack, thus it is hard to thwart combined attack, such as combined power and fault attacks. In this paper, we propose a dual complementary infection countermeasure for Advanced Encryption Standard (AES) cryptographic circuit to defend against both power and fault attacks. According to the target AES circuit, we first design and construct a dual complementary AES circuit to defend against power attacks, which can balance the power consumption when processing different data. Besides, to defend against fault attacks, in the dual complementary AES circuit, we design an improved random infection mechanism to diffuse the effect of injected faults. Experiment results show that the proposed countermeasure can thwart both power and fault attacks effectively. Compared with those AES circuits which can only defend against single attack, our designed circuit increases greatly the security under extra 83.1% area overhead and 2.1% impacts on the maximum working frequency. © 2019, The Korean Institute of Electrical Engineers.
