The course contains basic knowledge on two classes of finite-state dynamical systems --- finite automata and weighted automata. For the former, basic tools --- concurrent composition and observer will be introduced, how to use them to verify basic inference-based properties and concealment-based properties in discrete-event systems modelled by finite automata will be introduced as well. For the latter, only basic definitions will be introduced and compared over semirings and monoids. Students will acquire basic knowledge in control theory and computer science based on these two classes of systems, and will also catch a glimpse of similarities and differences between them.
Security issues of cyber-physical systems have drawn much attention in recent years. A system usually contains some secrets that are not expected to be exposed or hacked by unauthorized external intruders. In this 4-hour lectures, we introduce to students a general framework to secret protection in discrete-event systems. Our aim is to design an event-protecting policy such that any user, either legal or unauthorized, who visits a secret state must successfully executes/hacks a number of protected events to have an authorization satisfying the safety requirement. Two criteria of optimality (disruptiveness and cost) of designing protecting policies will be considered.
