    Post-quantum day of the cryptography seminar

    • November 20, 2026 (09:30 - 15:15)

    • Amphithéâtre E - Bâtiment 02A, Campus de Beaulieu - A map of the Beaulieu campus can be viewed at: https://www.univ-rennes.fr/en/beaulieu-campus-map (the building is south of the campus)

    A scientific day devoted to post-quantum cryptography, held in the wake of the European Cyber Week, with talks more technical than those presented at the ECW. The talks will take place at Amphi E in building 02A. To register for lunch, please do so before oct 30th using this link.

    Chiffrement homomorphe à l'aide des groupes après Nuida

    • November 27, 2026 (13:45 - 14:45)

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

    Speaker : Pierre Guillot - Ravel Technologies/Université de strasbourg

    Nuida et d'autres ont montré comment on peut obtenir un protocole de chiffrement pleinement homomorphe si l'on sait chiffrer les éléments d'un groupe G convenable, tout en sachant faire l'opération de G "en homomorphe".   Les exemples étaient jusqu'à présent limités au chiffrement d'un bit à la fois, avec beaucoup d'opérations à effectuer pour "simuler" les portes logiques usuelles. Je vais[…]

    Speaker : Russell Tessier - University of Massachusetts

    In this talk, we examine efforts to protect network processing and computation in cloud-based FPGAs from hardware- and software-based attacks. FPGAs have served as integral components in cloud computing for a decade, even though commercial FPGA architectures were not designed for cloud deployment. A range of potential attacks on cloud-based FPGAs and their remediations are examined. We[…]

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

    • February 12, 2027 (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[…]
