Countermeasures for Advanced Encryption Standard (AES) to thwart side-channel attack and fault attack are typically investigated in a separate fashion. There is lack of thorough investigation on how one countermeasure specifically for one attack affects the efficiency of another attack. In this work, we consider three different fault detection (FD) methods - double modular redundancy (DMR), inverse...
Driven by malicious intent, attackers are impelled to extract the cipher key and thus compromise the cryptosystem through fault attacks. Existing fault-detection methods can effectively detect random faults in the cipher implementation, but yield a high fault bypass rate (FBR) under intelligent fault attacks. To address this limitation, we propose a new microarchitecture to thwart fault attacks that...
The fourth fundamental circuit element, memristor, attracts increasing attention because of its memory characteristic. The special memory behavior of the memristor has been exploited to design control systems, memory arrays, logic gate, and security primitives in previous work. However, the power characteristics of the memristor have not been widely studied yet. In this work, we used a memristor model...
