    Should I trust or should I go? A deep dive into the (not so reliable) web PKI trust model

    • 19 décembre 2025 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Room Markov

    Orateur : Romain Laborde - University of Toulouse

    The padlock shown in the URL bar of our favorite web browser indicates that we are connected using a secure HTTPS connection and providing some sense of security. Unfortunately, the reality is slightly more complex. The trust model of the underlying Web PKI is invalid, making TLS a colossus with feet of clay. In this talk, we will dive into the trust model of the web PKI ecosystem to understand[…]

    Predicting Module-Lattice Reduction

    • 19 décembre 2025 (13:45 - 14:45)

    • Batiment 22-23 salle 14 (en face de l'amphi Lebesgue)

    Orateur : Paola de Perthuis - CWI

    Is module-lattice reduction better than unstructured lattice reduction? This question was highlighted as `Q8' in the Kyber NIST standardization submission (Avanzi et al., 2021), as potentially affecting the concrete security of Kyber and other module-lattice-based schemes. Foundational works on module-lattice reduction (Lee, Pellet-Mary, Stehlé, and Wallet, ASIACRYPT 2019; Mukherjee and Stephens[…]

    ML-Based Hardware Trojan Detection in AI Accelerators via Power Side-Channel Analysis

    • 16 janvier 2026 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Espace de conférences

    Orateur : Yehya NASSER - IMT Atlantique

    Our work discusses the security risks associated with outsourcing AI accelerator design due to the threat of hardware Trojans (HTs), a problem traditional testing methods fail to address. We introduce a novel solution based on Power Side-Channel Analysis (PSCA), where we collect and preprocess power traces by segmenting them and extracting features from both time and frequency domains. This[…]

    Attacking the Supersingular Isogeny Problem: From the Delfs–Galbraith algorithm to oriented graphs

    • 23 janvier 2026 (13:45 - 14:45)

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

    Orateur : Arthur Herlédan Le Merdy - COSIC, KU Leuven

    The threat of quantum computers motivates the introduction of new hard problems for cryptography.One promising candidate is the Isogeny problem: given two elliptic curves, compute a “nice’’ map between them, called an isogeny.In this talk, we study classical attacks on this problem, specialised to supersingular elliptic curves, on which the security of current isogeny-based cryptography relies. In[…]
