Mes travaux portent sur la cryptographie appliquée, la sécurité de l'IA, les systèmes résilients et l'investigation numérique. Ma thèse, soutenue au Cnam, portait sur l'apprentissage automatique sous chiffrement homomorphe dans les environnements IoT/cloud.
Thèmes de recherche
- Sécurité des agents IA et des RAG : injection indirecte, autorisation, gouvernance
- Ingénierie de la détection et purple teaming
- Cryptographie post-quantique et crypto-agilité
- Chiffrement homomorphe et apprentissage préservant la vie privée
- Traitement automatique du kabyle
