Design of S-boxes Defined with Cellular Automata Rules

2017

The aim of this paper is to find cellular automata (CA) rules that are used to describe S-boxes with good cryptographic properties and low implementation cost. Up to now, CA rules have been used in …

On Comparing Side-channel Properties of AES and ChaCha20 on Microcontrollers

2018

Side-channel attacks are a real threat to many secure systems. In this paper, we consider two ciphers used in the automotive industry - AES and ChaCha20 and we evaluate their resistance against side-channel attacks. In …

A Systematic Exploration of Evolutionary Computation for the Design of Hardware-oriented Non-cryptographic Hash Functions

2024 · Proceedings of the Genetic and Evolutionary Computation Conference

Non-cryptographic (NC) hash functions are crucial in high-speed search applications and probabilistic data structures (PDS) such as Bloom filters and Count-Min sketches for efficient lookups and counting. These operations necessitate execution at line rates to …
