Abstract: The constitution of nonlinear transformation S-box in AES Rijndael algorithm is analyzed. The affine permutation in the process of S-box construction is changed in order to construct a kind of 66 S-box with some good cryptographic properties, and the avalanche probabilities of these S-boxes are analyzed in the light of variance, and some rules are obtained from the analysis, which will help to find safer S-boxes.
