Security of GPS - INS Based On-Road Location Tracking Systems

Explore the vulnerabilities of GPS and INS-based location tracking systems for road transportation in this IEEE conference talk. Delve into algorithms that enable adversaries to travel to alternate locations undetected, despite INS-aided GPS monitoring. Examine the construction of graph models for road networks and the generation of spoofed routes that render gyroscope and accelerometer sensors ineffective. Learn about a real-time integrated GPS/INS spoofer that accounts for traffic conditions and dynamically generates spoofing signals. Analyze experimental results from ten different cities, revealing the potential for attackers to reach destinations up to 30 km away without detection. Discover proposed countermeasures to limit adversarial capabilities without hardware modifications. Gain insights into the security challenges facing location-based systems and potential solutions for enhancing their resilience against sophisticated attacks.
