CRYPTO : Sébastien Duval (Université Catholique de Louvain) : Construction of MDS and almost-MDS matrices with a lightweight circuit
Bâtiment Descartes, salle 301MDS matrices are essential in symmetric-key cryptography since they provide optimal diffusion in block ciphers. Many MDS matrices are known, but a problem remains which gathers a lot of attention: finding lightweight MDS matrices. Several approaches exist, namely reducing the
