GPS Spoofing and Cyber-Physical Security of Autonomous Vehicles
Abstract: The physical nature of cyber-physical systems creates new challenges for security and resiliency of autonomous systems. Traditional cybersecurity has focused on authentication, encryption, and other computer techniques, but the increased connectivity of systems and the inclusion of a wide variety of sensors create new avenues for attack and failure. In this talk, I will present the results of a class project where autonomous vehicles were subjected to GPS spoofing. For their term project, students in the class designed and built small, autonomous vehicles that relied on wheel encoders and data provided from a camera – an “indoor GPS” – for feedback. Students developed sensor fusion and control algorithms to localize the vehicles and navigate from point to point in a small arena. Unbeknownst to the students, however, the camera feedback system was “hacked” to systematically send erroneous coordinates during their final demonstrations for the purpose of observing the students’ reactions and assessing their awareness of such attacks. Despite the fact that the students had given presentations on cyber-physical security, including GPS spoofing, earlier in the term, only one student even considered such an attack as a potential cause of the obvious system anomalies, indicating that more attention needs to be placed on cyber-physical security so that the next generation of engineers are better able to detect and defend against potential threats.
Bio: Greg Lewin is an Assistant Professor in Engineering Systems and Environment at the University of Virginia, where he is Director of the Technology Leaders Program, an interdisciplinary engineering program that stresses design of integrated systems. He teaches courses in cyber-physical systems, robotics, and design. He also leads interdisciplinary capstone projects ranging from using in situ camera data to analyze the performance of 3d-printers to designing an autonomous rover for monitoring soil respiration in an agricultural setting. He received his Ph. D. in Mechanical and Aerospace Engineering from the University of Virginia, where he did research on flapping flight. More recently, he has engaged in research in sensor systems, robotics, and system modelling. In his spare time, he enjoys cycling and he’ll be happy to tell you about his extensive bicycle tours in Europe.
