    MIKE: An efficient and compact NIKE Based on a Commutative Monoidal Action 

    • July 03, 2026 (13:45 - 14:45)

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

    Speaker : Jonathan Komada Eriksen - COSIC, KU Leuven

    Robert recently described a powerful correspondence between certain (Hermitian) modules and (polarized) abelian varieties, which simultaneously generalizes both the class-group action underlying protocols such as CSIDH, and the Deuring correspondence, underlying protocols such as SQIsign. Using this correspondence, he also proposed how to construct a post-quantum NIKE, called MIKE, which, at a[…]

    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)

    • Inria Center of the University of Rennes - Room Markov

    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[…]

    Random lattices that are modules over the ring of integers

    • May 22, 2026 (13:45 - 15:45)

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

    Speaker : Nihar Gargava - Institut de Mathématiques d'Orsay

    We investigate the average number of lattice points within a ball where the lattice is chosen at random from the set of unit determinant ideal or modules lattices of some cyclotomic number field. The goal is to consider the space of such lattice as a probabilistic space and then study the distribution of lattice point counts. This is inspired by the connections of this problem to lattice-based[…]
