“…The verification of opacity has also been studied for different DES models including Petri nets [23], [33], [39], stochastic DES [8], [19], [43], [48], real-time systems [41] and networked DES [25], [45]. More recently, the notion of opacity has been extended to linear/nonlinear systems with infinite-states and continuous dynamics [1], [32], [49]. Compositional approaches have also been applied for the verification and synthesis of opacity for large-scale systems [27], [29]- [31].…”
