    Anomalies Mitigation for Horizontal Side Channel Attacks with Unsupervised Neural Networks

    • May 23, 2025 (10:00 - 11:00)

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

    Speaker : Gauthier Cler - SERMA Safety & Security

    The success of horizontal side-channel attacks heavily depends on the quality of the traces as well as the correct extraction of interest areas, which are expected to contain relevant leakages. If former is insufficient, this will consequently degrade the identification capability of potential leakage candidates and often render attacks inapplicable. This work assess the relevance of neural[…]

    Cryptanalytical extraction of complex Neural Networks in black-box settings

    • May 23, 2025 (11:00 - 12:00)

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

    Speaker : Benoit COQUERET - INRIA, Thales CESTI

    With the widespread development of artifical intelligence, Deep Neural Networks (DNN) have become valuable intellectual property (IP). In the past few years, software and hardware-based attacks targetting at the weights of the DNN have been introduced allowing potential attacker to gain access to a near-perfect copy of the victim's model. However, these attacks either fail against more complex[…]

    Fine-grained dynamic partitioning against cache-based side channel attacks

    • June 27, 2025 (10:00 - 11:00)

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

    Speaker : Nicolas Gaudin - Trasna

    The growth of embedded systems takes advantage of architectural advances from modern processors to increase performance while maintaining a low power consumption. Among these advances is the introduction of cache memory into embedded systems. These memories speed up the memory accesses by temporarily storing data close to the execution core. Furthermore, data from different applications share the[…]

    Side-Channel Based Disassembly on Complex Processors: From Microachitectural Characterization to Probabilistic Models

    • June 27, 2025 (11:00 - 12:00)

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

    Speaker : Julien Maillard - CEA

    Side-Channel Based Disassembly (SCBD) is a category of Side-Channel Analysis (SCA) that aims at recovering information on the code executed by a processor through the observation of physical side-channels such as power consumption or electromagnetic radiations. While traditional SCA often targets cryptographic keys, SCBD focuses on retrieving assembly code that can hardly be extracted via other[…]

    PhaseSCA: Exploiting Phase-Modulated Emanations in Side Channels

    • November 28, 2025 (10:00 - 11:00)

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

    Speaker : Pierre Ayoub - LAAS-CNRS

    In recent years, the limits of electromagnetic side-channel attacks have been significantly expanded.However, while there is a growing literature on increasing attack distance or performance, the discovery of new phenomenons about compromising electromagnetic emanations remains limited. In this work, we identify a novel form of modulation produced by unintentional electromagnetic emanations: phase[…]
