CySER Virtual Seminar – Cyber-physical system recovery from sensor attacks

About the event

Title: Cyber-physical system recovery from sensor attacks

Speaker: Dr. Mengyu Liu

Abstract: Cyber-Physical Systems (CPS) increasingly rely on sensor data to enable real-time decision making and safe control. However, their dependence on sensor inputs makes them vulnerable to malicious attacks that can compromise data integrity, leading to unsafe or unstable behavior. The key challenges lie in the real-time diagnosis of compromised sensors, the quantification of trust in redundant or alternative measurements, and the design of robust fallback strategies that ensure graceful degradation or safe control under degraded observability. Therefore, it is important to make sure the recovery method balances the control performance and timing constraints at the same time.
