    Les véhicules connectés intègrent de nombreuses technologies de communications sans-fil à distance, comme celles exploitant les protocoles Bluetooth ou WiFi. Si le gain en confort d’utilisation et d’interaction est notable, la mise à disposition de ce type d’interfaces augmente les risques en matière de cybersécurité. Dans cet article, nous analysons l’implémentation de la pile Bluetooth embarquée[…]

  • Conformité TEMPEST et compromission d’information au travers de l’arbre d’alimentation d’un équipement

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

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

    Speaker : Tristan PECHERAU, David HARDY - Thalès

    THALES conçoit des équipements cryptographiques et de radiocommunication tactiques, navales et aéronautiques, embarquant des éléments de chiffrement pour la sécurité des communications. Cette sécurité notamment d’un point de vue des émanations électromagnétiques est normée. Ces normes de sécurité de l’information, sont connues sous le nom de code “TEMPEST”, correspondant aux normes OTAN SDIP-27,[…]

  • Wagner’s Algorithm Provably Runs in Subexponential Time for SIS^∞

    • November 21, 2025 (13:45 - 14:45)

    Speaker : Johanna Loyer - Inria Saclay

    At CRYPTO 2015, Kirchner and Fouque claimed that a carefully tuned variant of the Blum-Kalai-Wasserman (BKW) algorithm (JACM 2003) should solve the Learning with Errors problem (LWE) in slightly subexponential time for modulus q = poly(n) and narrow error distribution, when given enough LWE samples. Taking a modular view, one may regard BKW as a combination of Wagner’s algorithm (CRYPTO 2002), run[…]

  • CHERIoT RTOS: An OS for Fine-Grained Memory-Safe Compartments on Low-Cost Embedded Devices

    • November 21, 2025 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Room Métivier

    Speaker : Hugo Lefeuvre - The University of British Columbia

    Embedded systems do not benefit from strong memory protection, because they are designed to minimize cost. At the same time, there is increasing pressure to connect embedded devices to the internet, where their vulnerable nature makes them routinely subject to compromise. This fundamental tension leads to the current status-quo where exploitable devices put individuals and critical infrastructure[…]

    • November 21, 2025 (10:00 - 11:00)

    • Inria Center of the University of Rennes - Room Métivier

    Speaker : Henrik Plate - Endor Labs

    Vulnerability databases play a crucial role in modern software security, serving as the backbone for Application Security (AppSec) and Software Composition Analysis (SCA) tools. However, the accuracy and reliability of these databases vary significantly, often leading to misinformed security decisions. This talk explores the challenges associated with vulnerability databases, including incomplete[…]

  • Some applications of linear programming to Dilithium

    • November 14, 2025 (13:45 - 14:45)

    • Salle 12 batimpent 32B

    Speaker : Paco AZEVEDO OLIVEIRA - Thales & UVSQ

    Dilithium is a signature algorithm, considered post-quantum, and recently standardized under the name ML-DSA by NIST. Due to its security and performance, it is recommended in most use cases.   During this presentation, I will outline the main ideas behind two studies, conducted in collaboration with Andersson Calle-Vierra, Benoît Cogliati, and Louis Goubin, which provide a better understanding of[…]
