Research thematics
The LRE “Security and Systems” group aims at securing IT systems in three areas:
- the identification of vulnerabilities
- the protection of software, operating systems and networks
- attack detection using Machine Learning and Graph Learning

It focuses on two major scientific issues:
- What are the best practices for creating robust and sustainable systems?
- What artificial intelligence tools (graphs, machine learning) are used to detect malicious actors and software?
The group team is interested in attacks targeting both the heart of systems (processors, kernels, operating systems) and those targeting industrial, embedded and distributed systems (5G, SCADA, blockchain).
Applications
The application domains cover:
- Operating Systems
- Malware analysis
- Internet of Things and 5G networks
- Blockchain
Collaborations
The members of the team are part of:
- UNITWin UNESCO Complex Systems Digital Campus
- ICube Laboratory at University of Strasbourg
We tightly collaborate with:
- College of Communication and Information University of Kentucky, Sherali Zeadally
- Laboratoire Traitement et Communication de l’Information (LTCI), Télécom Paris, Rida Khatoun
