Description de poste

Position and International Context :

We invite applications for a fully funded PhD research position in computer science co-supervised between University of Bordeaux, France, and KU Leuven, Belgium.

The French part of the Ph.D. thesis will take place within the Progress research group of LaBRI at the University of Bordeaux, France.

The Belgian part of the Ph.D. thesis will take place within the Computer Security and Industrial Cryptography (COSIC) research group of KU Leuven, Belgium.

The position is funded for 3 years and will address research challenges in the fields of physical layer authentication in distributed systems. When successful, the Ph.D. candidate will obtain a dual Ph.D. degree from both the University of Bordeaux and KU Leuven.

The research work will be conducted under the supervision of Dr. Dave Singelée (KU Leuven) and Dr. Stéphane Delbruel (University of Bordeaux), in the context of a collaboration between the two universities.

Scientific Context :

Mass adoption, among others within critical use cases, led to a strong need to provide security in wireless sensor networks (WSNs). In today’s infrastructures, this role tends to be handled by a core entity, using authentication and encryption provided by application layer-based secure mechanisms.

This approach, inherited from decades of wired network infrastructures, showed its limits and inadequacy when applied to WSNs. Facing energy constraints, limited computing power, and connectivity, it becomes of prime importance to investigate novel security mechanisms able to operate in a more pervasive fashion within the end-devices.

Physical (PHY) layer-based security is a novel and promising approach based on information-theoretic security, operating at the lowest level and providing secure mechanisms relying on physical phenomena of the radio link itself. Such mechanisms for constrained environments hold the promises of overcoming the previously cited limitations while potentially offering substantial energy savings.

Leveraging this emerging field of PHY-based security, we propose to investigate a novel network and system security paradigm, able to strengthen the authentication guarantees offered by any infrastructure operator while simplifying their implementation.
