Présentation du séminaire

  • Information systems and networks have become indispensable aids in our everyday lives. In addition to highly visible uses as mobile phones or personal computers, it is worth mentioning applications more subtle but equally important for economic activity such as cloud computing, industrial control systems, electrical networks. In fact, our society nurtures a growing dependence towards information systems which makes economic and sovereignty issues related to security increasingly important.

    At the same time, due to their increasing complexity, their ubiquity, and multiplicity of risks associated with malicious or fraudulent use, ensuring an acceptable level of security seems close to impossible. Many questions related to the control of the security of softwares and information systems are thus at the origin of an intense scientific activity. We can cite for example intrusion detection, vulnerability research, proof of protocols, static analysis, virtualization…

    From the interaction of all these themes, emerges a deep scientific domain that forms a point of contact between fundamental research and applications with a strong economic potential. Rennes metropolitan area is home to many talents in this field of research, both in academia and industry. This seminar aims to become a natural platform to gather, stimulate and promote Rennes security research and development community by confronting it to the best achievements of international research.

  • Opening Pandora's Box: White-Box Attacks on Microsoft's PhotoDNA Perceptual Hash Function

    • 05 juin 2026 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Aurigny room

    Orateur : Diane Leblanc-Albarel - KU Leuven

    PhotoDNA is a widely deployed perceptual hash function used for the detection of illicit content such as Child Sexual Abuse Material (CSAM). In this talk, I will present our paper introducing the first mathematical description of Alleged PhotoDNA, a function that reproduces the outputs of PhotoDNA. Our analysis reveals several structural weaknesses: the function is piece-wise linear and[…]

    Orateur : Raouf Kerkouche - Inria Lille

    Large Language Models (LLMs) have achieved considerable success and are now widely used across multiple domains, highlighting their transformative impact on both technology and society. However, this widespread adoption also exposes LLMs to numerous security threats that can alter model behavior or degrade overall performance. To mitigate these threats, most research has focused on alignment[…]

Privacy-preserving collaboration for intrusion detection in distributed systems

  • 27 mars 2026 (11:00 - 12:00)

  • Inria Center of the University of Rennes - Room Markov

Orateur : Léo Lavaur - Université du Luxembourg

The emergence of Federated Learning (FL) has rekindled the interest in collaborative intrusion detection systems, which were previously limited by the risks of information disclosure associated with data sharing. But is it a good collaboration tool? Originally designed to train prediction models on distributed consumer data without compromising data confidentiality, its use as a collaborative[…]
