FeFET based Logic-in-Memory design, methodologies, tools and open challenges
Speaker : 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
Speaker : 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
Speaker : 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
Speaker : 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[…]-

Acquisition and Exploitation of Traces from Connected Devices
Speaker : Francesco Servida - École des Sciences Criminelles, Université de Lausanne
This presentation aims to give an overview of the traces that can be obtained from connected objects as witnesses or actors at a crime scene. Using several scenarios we cover the challenges of detecting connected devices, the relevant locations for data retrieval and the techniques for acquiring said data. We then present how such data can be useful in helping to understand the dynamics of events[…]-

Understanding and fighting fault injections with programming languages
Speaker : Sébastien Michelland - Université Grenoble Alpes, Grenoble INP, LCIS
Would your latest program produce correct results if I skipped a statement in it? Two? Corrupted a variable at random? Then it might not be robust against _fault injection attacks_, which target hardware directly and have such effects. To be fair, nothing really resists them; still, efforts in designing protections have come a long way, relying (perhaps surprisingly) in large part on hardening[…]-
