Séminaire de l’équipe SARA “Physical-Layer Security of LEO Satellite Communication Links”, par Savio Sciancalepore, Senior Assistant Professor in Wireless IoT Security (Eindhoven University of Technology, Netherlands)

Résumé :

Satellite communication links have recently received renewed attention from the Industry and scientific community, especially for the Low-Earth Orbit (LEO), thanks to the increasingly low cost barriers required to launch and operate small satellites orbiting at low altitudes. At the same time, the growing dependence on LEO satellite links also amplifies their exposure to cyber threats.. Among these, attacks targeting the radio access layer pose significant challenges due to unique characteristics such as unencrypted and unauthenticated broadcast pilot channels, the physical distance between satellites and ground receivers, and legacy system constraints. To shed more light into the domain, this talk explores physical-layer security issues and mitigations for LEO satellite communication links. The talk will present applied practical work executed in a coordinated fashion among various universities worldwide, aiming at detecting attacks like spoofing and jamming of LEO satel! lite links through the modelling and analysis physical-layer information, e.g., In-Phase – Quadrature (IQ) samples. The talk will introduce several approaches, from device identification to channel fingerprinting, highlighting strengths and weaknesses of the various techniques and fostering dialogue on security practices relevant for both Industry and academic research.
