Security and systems Group

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).


The application domains cover:

  • Operating Systems
  • Malware analysis
  • Internet of Things and 5G networks
  • Blockchain


The members of the team are part of:

We tightly collaborate with:
