Executive Summary

In this paper, the authors present the equivalence of the operations involved in DES and AES algorithm with operations of cellular automata. They identify all the permutation and substitution operations involved in DES and AES algorithm and compare these operations with the cellular automata rules. Then they find that permutation operations involved in DES and AES are equivalent to linear cellular automata rules providing diffusion property of cryptography whereas substitution operations involved in DES and AES are equivalent to non linear cellular automata rules providing the confusion property of cryptography.
