Abstract

In this paper, current mode logic based on the three-independent-gate field effect transistor (TIGFET) is introduced as the circuit-level side-channel attack (SCA) countermeasures, and a SCA-resilience flip-flop (DyCML) is designed to make the power consumption constant. Then, a simplified advanced encryption system (AES) is built, and power analysis is performed to evaluate the SCA-resistance efficacy. Simulation results show that the key with the TIGFET-based DyCML is not revealed with 255 power traces. The proposed design occupies less area usage and requires less delay overhead compared to the original TIGFET-based true single-phase clock (TSPC) and modified TSPC (mTSPC).
