Generation and Optimization of Rijndael S-box Equation System
Jie Cui, Hong Zhong, Jiankai Wang and Runhua Shi

Abstract:
In this study, according to the inverse transformation principle and the affine transformation principle of Rijndael S-box, a new approach to generating the multivariate quadratic equation system over GF(2) is proposed and the generation process is given explicitly. According to the algebraic expression of the new Rijndael S-box, an equation system over GF(28) is proposed to describe Rijndael. By comparing with other existing systems, this system has stronger resistance against algebraic attacks. So, the equation system of the new Rijndael S-box is much securer than other existing equation systems.
