On the Difficulty of Constructing Cryptographically Strong Substitution Boxes
Two signi cant recent advances in cryptanalysis, namely the di erential attack put forward by Biham and Shamir [BS91] and the linear attack by Matsui [Mat94a, Mat94b], have had devastating impact on data encryption algorithms. An eminent problem that researchers are facing is to design S-boxes or substitution boxes so that an encryption algorithm that employs the S-boxes is immune to the attack...
متن کاملCryptographically Strong S-Boxes Generated by Modified Immune Algorithm
S-boxes play an important role in ensuring the resistance of block ciphers against cryptanalysis as often they are their only nonlinear components. The cryptographic properties of S-boxes and a variety of constructions have been studied extensively over the past years. Techniques for S-box generation include algebraic constructions, pseudo-random generation and heuristic approaches. The family ...

متن کاملDesigning cryptographically strong S-boxes with the use of cellular automata
Block ciphers are widely used in modern cryptography. Substitution boxes (S–boxes) are main elements of these types of ciphers. In this paper we propose a new method to create S–boxes, which is based on application of Cellular Automata (CA). We present the results of testing CA-based S–boxes. These results confirm that CA are able to realize efficiently the Boolean function corresponding to cla...
