TrustSoC : a heterogeneous secure-by-design SoC architecture
Orateur : Raphaële Milan - Université Jean Monnet Saint-Etienne, CNRS, Laboratoire Hubert Curien UMR 5516
Since the 1970s, the complexity of systems on a chip has grown significantly. In order to improve system performance, manufacturers are integrating an increasing number of heterogeneous components on a single silicon chip. The incorporation of these components renders SoCs highly versatile yet significantly complex. Their multipurpose nature makes them suitable for use in a variety of domains,[…]-

FeFET based Logic-in-Memory design, methodologies, tools and open challenges
Orateur : Cédric Marchand - University of Lyon - Lyon Institute of Nanotechnology (UMR CNRS 5270)
Data-centric applications such as artificial intelligence and the Internet of Things (IoT) impose increasingly stringent demands on the performance, the security and the energy efficiency of modern computing architectures. Traditional approaches are often unable to keep pace with these requirements making necessary to explore innovative paradigms such as in-memory computing. This paradigm is[…]-

Code Encryption for Confidentiality and Execution Integrity down to Control Signals
Orateur : Théophile Gousselot - Mines Saint-Etienne, CEA, Leti, Centre CMP, F - 13541 Gardanne France
Embedded devices face software and physical fault injections to either extract or tamper with code in memory. The code execution and code intellectual property are threatened. Some existing countermeasures provide Control Flow Integrity (CFI) extended with the confidentiality and integrity of the instructions by chaining all of them through a cryptographic encryption primitive. While tampering[…]-

The Battle Against Bots: Current Threats and New Directions to Counter Automated Attacks
Orateur : Elisa Chiapponi - Amadeus IT Group
In today's digital landscape, the battle between industry and automated bots is an ever-evolving challenge. Attackers are leveraging advanced techniques such as residential proxies, CAPTCHA farms, and AI-enhanced fingerprint rotations to evade detection and execute functional abuse attacks, including web scraping, denial of inventory, and SMS pumping. This talk will explore ongoing efforts to[…]-

From Deciding Knowledge to Intrusion Detection
Orateur : Yannick Chevalier - Université de Toulouse
By interpreting terms as distributions over strings, Abadi and Rogaway proved under suitable assumptions that indistinguishability in the computational setting, accepted as the impossibility for an observer to acquire knowledge from observing a protocol execution, is equivalent to formal equivalence in a symbolic setting. This result led to multiple results on “deciding knowledge” using static[…]-

Une approche langages pour comprendre et affronter les injections de fautes
Orateur : Sébastien Michelland - Université Grenoble Alpes, Grenoble INP, LCIS
Est-ce que votre dernier programme fonctionnerait si je sautais une ligne de code ? Deux ? Si je corrompais une variable aléatoirement ? Alors il ne résiste pas aux _attaques par injection de faute_, qui ciblent le matériel et produisent ce type d'effets. Pour être honnête, rien n'y résiste vraiment. Les efforts pour s'en protéger ont malgré tout bien progressé, principalement (et c'est peut-être[…]-
