Title: False Data Injection Attack Resilient Telerobotics

Abstract:

In this talk, the critical issue of False Data Injection Attacks (FDIAs) on networked robot control systems and novel strategies for enhancing their resilience are discussed. The talk introduces the concept of perfectly undetectable FDIAs based on affine transformations, demonstrating how these simplistic attacks can significantly alter a robot's behavior while evading detection by conventional methods. Perfectly undetectable FDIAs can be introduced not only on linear dynamic plants but also on a class of nonlinear robotic systems. To counter this threat, a defense mechanism based on state monitoring signature functions (SMSF) is proposed, designed to be resistant to affine transformations and capable of detecting manipulations in the system's state. The talk discusses encrypted adaptive control, exploring how homomorphic encryption (HE) techniques can be leveraged to secure control signals and state information without compromising system performance. A newly proposed security feature utilizing Somewhat Homomorphic Encryption (SHE) overflow traps is introduced, which exploits the mathematical properties of encryption schemes and is triggered when increased encryption noise is detected due to computational effort performed by the attacker for FDIA. The talk also covers practical implications of these security measures for real-world robotic applications such as remote manipulators and mobile robots.
