    HDL simulation for Masked Software Verification

    • May 29, 2026 (10:00 - 11:00)

    Speaker : Quentin Meunier - Sorbonne Univ. Lip6

    Masking is a countermeasure against Side-Channel Attacks (SCA) that aims to ensure that intermediate computations in an algorithm have secret-independent distributions through the use of random variables. This theoretically prevents SCAs, as power consumption is directly linked to the values manipulated by the program or hardware device. Designing a masking scheme is often non-trivial, and a[…]

    Étude, caractérisation et détection de verrouillage d'anneaux oscillants utilisés dans les générateurs de nombres aléatoires.

    • May 29, 2026 (11:00 - 12:00)

    • IETR - University of Rennes - Campus de BEAULIEU - Bâtiment 11D, salle numéro 18

    Speaker : Eloise Delolme - LabHC

    Les générateurs de nombres aléatoires matériels basés sur des oscillateurs en anneau (RO-TRNGs) exploitent le jitter d’horloge comme source d’aléa afin de produire des séquences de bits aléatoires. Parmi ces architectures, le MURO-TRNG repose sur un modèle stochastique complexe qui suppose notamment l’indépendance des oscillateurs. Toutefois, dans la pratique, les oscillateurs en anneau sont[…]

    Chamois: Formally verified compilation for optimisation and security

    • June 26, 2026 (10:00 - 11:00)

    • IETR - University of Rennes - Campus de BEAULIEU - Bâtiment 11D, salle numéro 18

    Speaker : David MONNIAUX - CNRS - Verimag

    Embedded programs (including those on smart cards) are often developed in C and then compiled for the embedded processor. Sometimes they are modified by hand to incorporate countermeasures (fault attacks, etc.), but care must be taken to ensure that this does not disrupt normal program execution and that the countermeasure is actually adequate for blocking the attacks.In the process, it is[…]

    Security of Smart Dust: Robust Key Derivation for Single-Chip Systems

    • June 26, 2026 (11:00 - 12:00)

    • IETR - University of Rennes - Campus de BEAULIEU - Bâtiment 11D, salle numéro 18

    Speaker : Sara Faour - Inria

    The Smart Dust vision seeks to enable large networks of millimeter-scale wireless sensor nodes that tightly integrate sensing, computation, communication, and power management into a single-chip device. Establishing a robust hardware root of trust for such devices remains challenging, particularly in single, low-cost chip manufacturing processes that lack embedded writable Non-Volatile Memory (NVM[…]

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

    • October 16, 2026 (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[…]
