Title: Securing Next-generation Autonomous Cyber-physical Systems


The future is autonomous and cyber-physical systems will play a critical role in it. With their imminent integration and deployment into safety- and security-critical applications such as transportation, healthcare, and energy, it is important to ensure the resilience of these systems to attacks. Cyber-physical systems are a conglomeration of a variety of physical sensing, computing and communication technologies. Therefore, they are vulnerable to a wider range of attacks and security needs to become an integral part of the system’s design. In other words, there is a strong need to build secure sensing, computing and communication technologies without compromising on their performance guarantees.

In this talk, I will present my recent works on securing modern-day autonomous cyber-physical systems. First, location and time are critical to a wide-variety of applications (e.g., autonomous cars, drones) and today's systems are vulnerable to location spoofing attacks. I will introduce SPREE, the first spoofing resilient GPS receiver capable of limiting even the strongest of attackers known in the literature. Second, I will address the problem of guaranteeing timing properties in mixed-criticality systems in the scenario of partial hardware and software compromise. Third, I will briefly demonstrate the practical limits of isolation achievable on multi-core computing platforms which are today increasingly used in building autonomous systems. Finally, I will discuss open challenges and research opportunities that lie ahead enabling a secure and safe autonomous cyber-physical future.


Aanjhan is currently a post-doctoral researcher in the System Security Group at ETH Zurich. He obtained his PhD in 2016 under the supervision of Prof. Dr. Srdjan Capkun. His research mostly revolves around the physical-layer security of wireless systems (e.g., secure localization and ranging, GPS security, (anti-) jamming techniques). His research on security of GPS was awarded the Swiss regional prize for innovative technolgies by the European Space Agency. His doctoral dissertation on “Physical-layer Techniques on Secure Proximity Verification and Localization Techniques” was awarded the ETH medal. In the past, he has worked on computer architectures, specifically, multiprocessor systems, cache coherency protocols and communication bus protocols. Prior to joining the System Security group at ETH Zurich, he worked at Robert Bosch GmbH's Car Multimedia Division "Blaupunkt" for over 3 years involved in research and development of embedded modules for top automotive manufacturers including Audi and Volkswagen.
