In this work, a novel asynchronous combinational S-Box (substitution box) design for AES (Advanced Encryption Standard) cryptosystems is projected and validated. The S-Box is examined because the final vital component in AES crypto-circuits since it employs the foremost power and leaks the most information contrary to side-channel attacks. The proposed technique is based on a delay-insensitive logic paradigm referred to as Null Conventional Logic (NCL).The projected NCL S-Box provides vast benefits over existing designs since it consumes less power therefore suited for energy control mobile crypto-applications. It also emits less noise and has blandish 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 AES asynchronous S-Box design
