We provide an exhaustive experimental analysis of the proposed CA-based S-boxes in terms of non-linearity, autocorrelation, balance and strict avalanche criterion, and compare results with ones corresponding to DES S-boxes. We show that the proposed CA-based S-boxes have cryptographic properties comparable to or better than classical S-box tables. The interesting feature of the proposed S-boxes is a dynamic flexible structure fully functionally realized by CA, while the classical DES S-boxes are represented by predefined unchangeable table structures.
