Topic: Securing Cyber-Physical Systems by Platform Reboot
Time: 1:00pm – 1:50 pm EST

Description: In this talk, the presenter will discuss techniques to secure cyber-physical systems (CPS) against cyberattacks, especially those are focused on causing physical damage to the plants. Physical plants that form the core of CPS have stringent safety requirements. The presenter will present their ideas on ensuring the “safety” of the physical plant even when the platform is compromised. In particular, the presenter will present two different approaches to achieve this goal: (a) restart-based mechanism, which utilizes complete system restarts and software reloads, and (b) hypervisor-based design that utilizes Trusted Execution Environment (TEE) such as ARM TrustZone.
