Authenticated UWB-Based Positioning of Passive Drones

Abstract

Drones can be downed by spoofing attacks. As a countermeasure, the European Space Agency has adopted a broadcast authentication protocol called Timed Efficient Loss-tolerant Authentication (TESLA) in the European Global Navigation Satellite System (GNSS), Galileo. In this work, we will assess the potential of using TESLA for indoor positioning systems that are based on ultra-wideband (UWB) technology. The initial findings from our experiments indicate that authentication methods based on TESLA can provide protection to an UWB-based indoor positioning system against signal spoofing,
