A novel systematic byte substitution method to design strong bijective substitution box (S-box) using piece-wise-linear chaotic map [PDF]
PeerJ Computer Science, 2022 Cryptography deals with designing practical mathematical algorithms having the two primitive elements of confusion and diffusion. The security of encrypted data is highly dependent on these two primitive elements and a key.

Highly dispersive substitution box (S‐box) design using chaos [PDF]
ETRI Journal, 2020 Highly dispersive S‐boxes are desirable in cryptosystems as nonlinear confusion sub‐layers for resisting modern attacks. For a near optimal cryptosystem resistant to modern cryptanalysis, a highly nonlinear and low differential probability (DP) value is ...

A secure key dependent dynamic substitution method for symmetric cryptosystems [PDF]
PeerJ Computer Science, 2021 The biggest challenge for symmetric cryptosystems is to replace their static substitution with dynamic substitution, because static substitution S-boxes make the symmetric block ciphers more vulnerable to attacks.

A method for generation of substitution box based on random selection
Egyptian Informatics Journal, 2022 Two basic requirements must be met to encrypt data. These requirements are confusion and diffusion properties. In particular, block cipher algorithms are based on a cryptographic component known as substitution-box to provide the need for confusion ...

Pareto-optimal hardware for substitution boxes [PDF]
International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II, 2005 En este trabajo, proponemos una metodología basada en la programación genética para generar automáticamente diseños de hardware de cajas de sustitución necesarias para muchos criptosistemas como el sistema de cifrado DES. Nuestro objetivo es desarrollar especificaciones de hardware mínimas, que minimicen tanto el espacio (es decir, el número de puerta ...
