Current Pass Optimized-Symmetric Pass Gate Adiabatic Logic in Countermeasures against Power Analysis Attacks
Hiroki Koyasu, Yasuhiro Takahashi · 2018
In this paper, we propose a new adiabatic logic for cryptographic circuits, called as Current Pass Optimized Symmetric Pass Gate Adiabatic Logic (CPO-SPGAL). The proposed circuit realizes a flat current waveform by considering the current path. From the simulation results, the proposed circuit can reduce the current fluctuation by about 37% and reduce the energy consumption fluctuation by about 62% than the existing SPGAL circuit. The simulation result shows also that; hence the proposed circuit is more resistant to differential power analysis attack than the existing circuit.
