FPGA Implementation of -Linear Pseudorandom Number Generators Based on Zynq MPSoC: a Chaotic Iterations Post Processing Case Study
Mohammed Bakiri, Jean-François Couchot, Christophe Guyeux
Pseudorandom number generation (PRNG) is a key element in hardware security platforms like field-programmable gate array FPGA circuits. In this article, 18 PRNGs belonging in 4 fam…
A Second Order Derivatives based Approach for Steganography
Jean-François Couchot, Raphaël Couturier, Yousra Ahmed Fadil +1
Steganography schemes are designed with the objective of minimizing a defined distortion function. In most existing state of the art approaches, this distortion function is based o…
Binary Particle Swarm Optimization versus Hybrid Genetic Algorithm for Inferring Well Supported Phylogenetic Trees
Bassam AlKindy, Bashar Al-Nuaimi, Christophe Guyeux +4
The amount of completely sequenced chloroplast genomes increases rapidly every day, leading to the possibility to build large-scale phylogenetic trees of plant species. Considering…
Quality Analysis of a Chaotic Proven Keyed Hash Function
Jacques M. Bahi, Jean-François Couchot, Christophe Guyeux
Hash functions are cryptographic tools, which are notably involved in integrity checking and password storage. They are of primary importance to improve the security of exchanges t…
Neural Networks and Chaos: Construction, Evaluation of Chaotic Networks, and Prediction of Chaos with Multilayer Feedforward Networks
Jacques M. Bahi, Jean-François Couchot, Christophe Guyeux +1
Many research works deal with chaotic neural networks for various fields of application. Unfortunately, up to now these networks are usually claimed to be chaotic without any mathe…
Steganalyzer performances in operational contexts
Yousra A. Fadil, Jean-François Couchot, Raphaël Couturier +1
Steganography and steganalysis are two important branches of the information hiding field of research. Steganography methods consist in hiding information in such a way that the se…
