Current Pass Optimized Symmetric Pass Gate Adiabatic Logic for Cryptographic Circuits

Abstract

We propose a new adiabatic logic for cryptographic circuits, called as the Current Pass Optimized Symmetric Pass Gate Adiabatic Logic (CPO-SPGAL). The proposed circuit realizes a flat current waveform by considering the current path. The simulation results demonstrate that the proposed circuit can reduce the current fluctuation by approximately 84% and reduce the energy consumption fluctuation by approximately 79% as compared to the existing SPGAL circuits. This shows that it is more resistant to differential power analysis attacks than conventional circuits.
