  Schéma de signature à clé publique : Frobénius-UOV

  • May 29, 2026 (13:45 - 14:45)

  • IRMAR - Université de Rennes - Campus Beaulieu Bat. 22, RDC, Rennes - Amphi Lebesgue

  Speaker : Gilles Macario-Rat - Orange

  L'exposé présente un schéma de signature à clé publique post-quantique inspiré du schéma UOV et introduisant un nouvel outil : les formes de Frobénius. L'accent est mis sur le rôle et les propriétés des formes de Frobénius dans ce nouveau schéma : la simplicité de description, la facilité de mise en oeuvre et le gain inédit sur les tailles de signature et de clé qui bat RSA-2048 au niveau de[…]

  Privacy-preserving collaboration for intrusion detection in distributed systems

  • March 27, 2026 (11:00 - 12:00)

  Speaker : Léo Lavaur - Université du Luxembourg

  The emergence of Federated Learning (FL) has rekindled the interest in collaborative intrusion detection systems, which were previously limited by the risks of information disclosure associated with data sharing. But is it a good collaboration tool? Originally designed to train prediction models on distributed consumer data without compromising data confidentiality, its use as a collaborative[…]

  Post-Quantum Cryptography Accelerated by a Superscalar RISC-V Processor

  • April 24, 2026 (11:00 - 12:00)

  • IETR - University of Rennes - Campus de BEAULIEU - Bâtiment 11D, salle numéro 18

  Speaker : Côme Allart - Inria

  Two major changes are currently taking place in the embedded processor ecosystem: open source with the RISC-V instruction set, which could replace the ARM one, and post-quantum cryptography (PQC), which could replace classic asymmetric cryptography algorithms to resist quantum computers.In this context, this thesis investigates the improvement of embedded processor performance, generally for[…]

  Protection des processeurs modernes face à la vulnérabilité Spectre

  • April 24, 2026 (10:00 - 11:00)

  • IETR - University of Rennes - Campus de BEAULIEU - Bâtiment 11D, salle numéro 18

  Speaker : Herinomena ANDRIANATREHINA - Inria

  Dans la quête permanente d'une puissance de calcul plus rapide, les processeurs modernes utilisent des techniques permettant d'exploiter au maximum leurs ressources. Parmi ces techniques, l'exécution spéculative tente de prédire le résultat des instructions dont l'issue n'est pas encore connue, mais dont dépend la suite du programme. Cela permet au processeur d'éviter d'être inactif. Cependant,[…]

  Securing processor's microarchitecture against SCA in a post-quantum cryptography setting

  • October 16, 2026 (10:00 - 11:00)

  • IETR - University of Rennes - Campus de BEAULIEU - Bâtiment 11D, salle numéro 18

  Speaker : Vincent MIGLIORE - LAAS-CNRS

  Hardware microarchitecture is a well-known source of side-channel leakages, providing a notable security reduction of standard cryptographic algorithms (e.g. AES) if not properly addressed by software or hardware. In this talk, we present new design approaches to harden processor's microarchitecture against power-based side-channel attacks, relying on configurable and cascadable building blocks[…]
