Lightweight 8‐bit S‐box and combined S‐box/S‐box−1 for cryptographic applications
International Journal of Circuit Theory and Applications, 2021SummaryIn this paper, a lightweight 8‐bit S‐box and combined S‐box/S‐box−1 with a security level equal to the AES S‐box is presented. From the viewpoint of hardware implementation, the S‐box has better hardware and timing complexities. The structure is based on an efficient field inversion and a low‐cost affine transformation. The field multiplications

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.
