Présentation
Après une thèse au CEA - Leti à Grenoble entre 2017 et 2020, j'ai effectué un postdoc au sein du groupe Crypto de l'Université catholique de Louvain (Louvain-la-neuve, Belgique). Je suis désormais chargé de recherche CNRS au sein de l'équipe SmartIES du Laboratoire d'Informatique, de Robotique et de Microélectronique de Montpellier (LIRMM). Ma recherche porte sur l'analyse des attaques par canaux auxiliaires contre les implémentations d'algorithmes de chiffrement. Je m'intéresse en particulier à l'usage des techniques d'apprentissage machine appliqué à une classe d'atttaques spécifiques : les attaques par profilage.
