Secure Positioning (Localization)

Positioning services are typically used for navigation and tracking. In a navigation scenario, an infrastructure (e.g., GPS) typically broadcasts signals that a device uses to compute its location. In a tracking scenario, it is often the device that transmits beacon messages to allow the infrastructure to compute its location e.g., using Time-Difference-of-Arrival (TDoA). Future is expected to be dominated by mobile systems, autonomous systems, robots and cyber-physical systems that will heavily rely on relative and absolute position information. Their use in security and safety critical applications mandates that the distance and position information that they calculate cannot be influenced by the attackers, as well as that compromised systems cannot influence the measurements of their own positions. We therefore need a new approach to the design of positioning systems that takes security requirements into account from the very start, and also accounts for the way that positioning systems are built and used. In this project, we address fundamental questions related to building secure positioning infrastructure.
