Study of self-healing mechanisms for embedded systems

While topics around protection mechanisms or threat detection are currently well covered, post-attack repair is still not very present in the scientific literature. Objectives: The objective of this thesis is to identify solutions to restore critical functions or tasks of an embedded device after the detection of an unwanted event (due to a malicious attack […] >>

Advanced side channel applied on post-quantum cryptography

The development of quantum computing threatens asymmetric cryptography. To address this threat, post-quantum cryptography (PQC) schemes, i.e. based on quantum computer resistant problems, have been proposed. The third round of the NIST PQC competition ended on July 5, 2022. The CRYSTALS-Kyber algorithm was selected for standardization. The history of cryptographic algorithms standardization shows that it […] >>

Assessment of Passive Radio Perturbations against Wireless Systems using Reconfigurable Surfaces

Reconfigurable Intelligent Surfaces (RISs), which consist of nearly-passive controllable devices (behaving as e.g., electromagnetic mirrors, lenses, or large sensing surfaces), have already shown promising potential to boost -or even sometimes just to enable- data communication and localization capabilities in next-generation wireless networks, while limiting the need of active base stations. Conversely, RISs could also be […] >>

Hardware and software signal extraction for power grid resilience

Power grid is the heart of recent concerns due to climate, economic and geostrategic risks. If the safety and performance of these systems are essential subjects to study, the resilience of energy systems to cyber-attacks is an issue that cannot be ignored. Indeed, energy systems are now the target of computer attacks carried out by […] >>

Management of Spectre and Meltdown information leaks in a RISC V application processor

Since 2018 and the announcement of the Spectre and Meltdow vulnerabilities, the hard-won performance gains of desktop and server processors over the past few decades have been called into question. These vulnerabilities effectively exploit the speculative and out of order execution found in all modern processors to gain in the number of instructions performed per […] >>
