ABSTRACT
AES type S-boxes are constructed by replacing the affine matrix of AES S-box equation with 8x8 invertible affine matrices. The 8x8 S-boxes of AES produced in GF (28) are a nonlinear transformation that have significant effect on the strength of entire system. In this paper, 46 AES like S-boxes are generated by replacing the affine matrix and only 10 randomly selected S-boxes are included. The cryptographic properties of 10 AES like S-boxes are analyzed. The S-box must satisfy these properties in order to yield a secure and reliable cipher. These include: Avalanche, Strict Avalanche, Bit Independence criteria and Non-linearity measurement. The experimental results indicate that most of the generated S-boxes mimic the AES original S-box with respect to these properties and some of them are stronger than AES S-box.
