Abstract
The problem of covert sensor-actuator attack synthesis in the context of network discrete-event system (DES) is studied, in which the observation channel and control channel have bounded delays. We investigate a kind of attack that can 1) keep hidden, 2) implement sensor insertion, deletion and replacement attacks, and actuator enablement and disablement attacks. We propose a transformation-based method to convert the covert attack synthesis problem of network DES into the standard Ramadge-Wonham supervisory control problem. Our method is applicable to the damage-reachable goal and damage-nonblocking goal.
