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

    • 16 janvier 2026 (11:00 - 12:00)

    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[…]

  • Predicting Module-Lattice Reduction

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

    • Batiment 22-23 salle 16 (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[…]

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

    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[…]

  • Post-Quantum Public-Key Pseudorandom Correlation Functions for OT

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

    • Salle Guernesey à l'ISTIC

    Orateur : Mahshid Riahinia - ENS, CNRS

    Public-Key Pseudorandom Correlation Functions (PK-PCF) are an exciting recent primitive introduced to enable fast secure computation. Despite significant advances in the group-based setting, success in the post-quantum regime has been much more limited. In this talk, I will introduce an efficient lattice-based PK-PCF for the string OT correlation. At the heart of our result lie several technical[…]

  • Hardware-Software Co-Designs for Microarchitectural Security

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

    • Inria Center of the University of Rennes - Room Petri/Turing

    Orateur : Lesly-Ann Daniel - EURECOM

    Microarchitectural optimizations, such as caches and speculative out-of-order execution, are essential for achieving high performance. However, these same mechanisms also open the door to attacks that can undermine software-enforced security policies. The current gold standard for defending against such attacks is the constant-time programming discipline, which prohibits secret-dependent control[…]
