Abstract: Cyber-Physical Systems that interconnect continuous physical processes and discrete controlling embedded computers by a complex communication network appear in almost every aspect of daily life: transportation, energy, medical systems, and food production. In this talk, I will address the challenges of developing mathematically rigorous frameworks and computationally feasible algorithms for the synthesis, analysis, and verification of attack-resilient, privacy-guarantee, and secure cyber-physical systems. First, I will present new controllability theorems for discrete event systems under regular-rewriting attacks with or without occasional authentications. Then, I will give several results on the trade-off between differential privacy and performance, as well as optimal mechanisms in distributed dynamical systems. Finally, I will introduce a novel framework for verifying cyber-physical systems via model reduction and statistical algorithms.
