Substitution Box Optimization

, 2019
The basic principle of encryption is to transform plain data into unintelligible data via a series of steps referred to as an encryption algorithm. The input to this algorithm is called plaintext, and its output encoded version is called as cipher text.

From Schreier graphs to secure s-boxes using a group-theoretic design framework [PDF]

Scientific Reports
Secure substitution boxes (S-boxes) are a fundamental design element of modern symmetric cryptography because they provide the necessary nonlinearity to achieve confusion.

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.

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 ...
