Cybersecurity

Overview

• Assured CPS autonomy applications
  • CPSs consist of both logical elements such as embedded computers and physical elements connected by communication channels such as Internet.
  • A wide range of safety critical CPSs, from an autonomous systems (e.g., UAS) to human-machine interaction (HMI) systems, and to networked systems (e.g., ATC, Smart Power Grid)
  • Each requires elaborate control tasks under different operating condition

=> Conventional control methods could not be directly applicable to assure the CPS

• Develop a unified control framework for assured CPS autonomy

• Focus of Our Research: Cyber-Physical Security and Safety of CPS
  • Research in Cyber Security from Computer Science Perspective
    • Key component of hardware/software layer in computer controlled system
    • Do not address the dynamical behavior of the CPS under cyber attacks
  • Scope of this study: Secure control theoretic perspective
    • Using the information about the dynamical model of the CPSs: Model-based approach
    • We do not enumerate the methods of cyber attacks; rather we focus on the resulting damage to the CPS dynamics if some data used is corrupted by cyber attacks.

• Development of a Cyber-Secure CPS Architecture against Cyber Attacks
  • Software/Hardware-in-the-Loop Analysis of Cyber Attacks on UAS [1]
  • Analysis and Design of Stealthy Cyber Attacks on UAS
  • Cyber Attack Mitigation for CPS: Hybrid System Approach to Controller Design
  • Real-Time Safety Assessment of UAS against Stealthy Cyber Attacks
  • Reachability Analysis for Safety Assurance of CPS against Cyber Attacks
  • Towards Cyber-Physical Vetting of Critical Infrastructures
