A 10-bit S-box generated by Feistel construction from cellular automata
Thomas Prévost, Bruno Martin
We propose a new 10-bit S-box generated from a Feistel construction. The subpermutations are generated by a 5-cell cellular automaton based on a unique well-chosen rule and bijecti…

An ETSI GS QKD compliant TLS implementation
Thomas Prévost, Bruno Martin, Olivier Alibart
A modification of the TLS protocol is presented, using our implementation of the Quantum Key Distribution (QKD) standard ETSI GS QKD 014 v1.1.1. We rely on the Rustls library for t…

Testing a cellular automata construction method to obtain 9-variable cryptographic Boolean functions
Thomas Prévost, Bruno Martin
We propose a method for constructing 9-variable cryptographic Boolean functions from the iterates of 5-variable cellular automata rules. We then analyze, for important cryptographi…
