Abstract : In this work,a novel asynchronous combinational S-Box (substitution box) design for AES(Advanced Encryption Standard) cryptosystems is proposed and validated.The S-Box is examined as the ultimate critical component in AES crypto-circuits since it employ the most power and leaks the most information contrary to side-channel attacks.The prospective design is based on a unresponsive logic paradigm known as Null Conventional Logic (NCL).The proposed NCL S-Box provides vast benefits over existing designs since it consumes less power therefore suited for energy constraint mobile crypto-utilizations.It also emanates less noise and has grace power peaks therefore leaks less information against side-channel attacks such as differential power/noise analysis.Functional verification and power measurement of NCL S-Box have been done using Mentor Graphics EDA (Electronic Design Automation ) tool to assure low-power side-channel attack-resistant operation of the proposed clock-free AES S-Box design.
