Nowadays, Linear redundancy has been identified in all S- boxes generated from finite field inversion and power mappings. That means it may be used in a new cryptanalytic attack in the future. In our study, we have developed an application to show that all output functions of an S-box are equivalent under an affine transformation of the input bits.

Cellular Automata-Based S-Boxes vs. DES S-Boxes
2009In the paper we use recently proposed cellular automata (CA) - based methodology [9] to design 6x4 S-boxes functionally equivalent to S-boxes used in current cryptographic standard known as DES. We provide an exhaustive experimental analysis of the proposed CA-based S-box in terms of non-linearity, autocorrelation, balance and strict avalanche ...

Substitution-Box (S-BOX) is the most critical block in the Advanced Encryption Standard (AES) algorithm, consumes 75% of total power during encryption. The primary idea to implement S-BOX is to have a unique byte substitution. In this paper 4 different architecture of SBOX discussed; (a) look-up table or ROM based S-BOX contains a pre-computed value ...

New Area Record for the AES Combined S-Box/Inverse S-Box
2018 IEEE 25th Symposium on Computer Arithmetic (ARITH), 2018The AES combined S-box/inverse S-box is a single construction that is shared between the encryption and decryption data paths of the AES. The currently most compact implementation of the AES combined S-box/inverse S-box is Canright's design, introduced back in 2005.

On the Algebraic Expression of the AES S-Box Like S-Boxes
2010In the literature, there are several proposed block ciphers like AES, Square, Shark and Hierocrypt which use S-boxes that are based on inversion mapping over a finite field. Because of the simple algebraic structure of S-boxes generated in this way, these ciphers usually use a bitwise affine transformation after the inversion mapping.

Improving quality of DES S-boxes by cellular automata-based S-boxes
The Journal of Supercomputing, 2010In the paper we use recently proposed cellular automata (CA) based methodology (Szaban and Seredynski in LNCS, vol. 5191, pp. 478---485, 2008) to design the 6×4 S-boxes functionally equivalent to S-boxes used in current cryptographic standard known as Data Encryption Standard (DES).

Efficient implementations of S-box and inverse S-box for AES algorithm
TENCON 2009 - 2009 IEEE Region 10 Conference, 2009In this paper, improved architectures are proposed for implementation of S-Box and inverse S-Box needed in the Advanced encryption standard (AES) algorithm. These use combinational logic only for implementing SubByte (S-box) and InvSubByte (Inverse S-box).
