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[…]-

Acquisition and Exploitation of Traces from Connected Devices
Orateur : 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[…]-

Side Channel Analysis: Instruction extraction and Information estimation
Orateur : Valence Cristiani
Side-channel usually aims at extracting cryptographic secrets from electronic devices through their physical leakages. However, these channels can leak other sensitive information. The first part of this talk will present a study of side channel-based disassembling (SCBD) that aims to recover instructions executed by a microcontroller. The main threat represented by SCBD is that it potentially[…] -
Security challenges and opportunities in emerging device technologies: a case study on flexible electronics
Orateur : Nele Mentens - KU Leuven, Belgium
While traditional chips in bulk silicon technology are widely used for reliable and highly ef?cient systems, there are applications that call for devices in other technologies. On the one hand, novel device technologies need to be re-evaluated with respect to potential threats and attacks, and how these can be faced with existing and novel security solutions and methods. On the other hand,[…] -
Bridging Deep Learning and Classical Profiled Side-Channel Attacks
Orateur : Gabriel Zaid
Over the recent years, the cryptanalysis community leveraged the potential of research on Deep Learning to enhance attacks. In particular, several studies have recently highlighted the benefits of Deep Learning based Side-Channel Attacks (DLSCA) to target real-world cryptographic implementations. While this new research area on applied cryptography provides impressive result to recover a secret[…] -
Implémentations sécurisées et évaluation pré-silicium contre les attaques physiques.
Orateur : Sofiane Takarabt
Side-channel attacks remain a permanent threat against embedded systems, thus reliable protections should be implemented and must be minutely evaluated. In this presentation, we study different possible ways to evaluate against such threats. We show how an evaluation can be carried out to validate a security level of a protected hardware implementation. This approach allows us to estimate in[…]
