S-Box is the only non-linear component in Advanced Encryption Standard(AES) which determine its strength.The Look-Up Table based S-Box of conventional AES occupies large storage space, reduced throughput and consumes more power.This article presents the design of an S-Box based on Reversible Cellular Automata function that reduces the implementation cost.Further, Cellular Automata functions are derived from various rules that are non-linear and S-Box properties are discussed briefly in this paper.With this approach, the time consumption for the AES S-Box is considerably decreased without compromising the nonlinearity of conventional S-Box.
