In this paper, 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.
