A Substitution Box for Lightweight Ciphers to Secure Internet of Things
Journal of King Saud University - Computer and Information Sciences, 2022 The Internet of Things is a resource-constrained device that demands lightweight cryptographic solutions to achieve high performance and optimal security. In lightweight ciphers Substitution Box (S-box) plays an important role as it enables confusion property. However, it is one of the costlier operations.

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 ...

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.

Design of Nonlinear Component of Block Cipher Using Gravesian Octonion Integers
IEEE Access, 2023 Being the only nonlinear component in many cryptosystems, an S-box is an integral part of modern symmetric ciphering techniques that creates randomness and increases confidentiality at the substitution stage of the encryption.
