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

    • December 19, 2025 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Room Markov

    Speaker : 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[…]

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

    • January 16, 2026 (11:00 - 12:00)

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

    Speaker : 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[…]
