Security of Radio-Based Positioning Systems - GNSS, 5G, and UWB

Explore a conference talk from INSAIT 2022 that delves into the security challenges of positioning systems across GNSS, 5G, and UWB technologies. Learn how radio interfaces provide proximity, distance, and location information to devices, and understand the vulnerabilities in systems like contactless payments, keyless entry, digital contact tracing, and autonomous navigation. Examine how attackers can manipulate distance or position information through relays and physical-layer attacks, potentially leading to property theft, financial losses, physical damage, or service disruption. Discover how these security concerns have influenced radio designs and standards, particularly in UWB, WiFi, and 5G implementations. Gain insights into the first commercially deployed distance measurement radios specifically designed to counter physical-layer attacks in the automotive industry. The presentation covers key challenges, existing solutions, ongoing research, and standardization efforts, with particular emphasis on UWB ranging solutions currently implemented in cars and smartphones.
