Abstract

The charge recovery logic families have been designed several years ago not in order to eliminate the side-channel leakage but to reduce the power consumption. However, in this article we present a new charge recovery logic style not only to gain high energy efficiency but also to achieve the resistance against side-channel attacks especially against differential power analysis attacks. Our approach is a modified version of a classical charge recovery logic style namely 2N-2N2P. Simulation results show a significant improvement in DPA-resistance level as well as in power consumption reduction in comparison with 2N-2N2P and other DPA-resistant logic styles.
