Pure Dynamic S-box Construction

Abstract: The S-box or substitution table used to provide non-linearity to encrypting algorithm. There are two types of S-box design such as Static S-box and Dynamic S-box. This paper reviews and analyses the efficiency of Dynamic S-box over Static S-box. This proposed approach has two fold, first fold is to design a Dynamic S-box based on the one-dimensional chaotic map (logistic and PWLCM) and compare to the classical S-box in terms of on confusion. Second fold is to calculate the one-dimensional map equation to construct Dynamic S-box. Finally analyse the properties of S-box on the constructed key-dependent Dynamic S-box.
