    On opacity verification for discrete-event systems

  • Original language description

    Opacity is an information flow property characterizing whether a system reveals its secretto an intruder. Verification of opacity for discrete-event systems modeled by automata is in general ahard problem. We discuss the question whether there are structural restrictions on the system modelsfor which the opacity verification is tractable. We consider two kinds of automata models: (i) acyclicautomata, and (ii) automata where all cycles are only in the form of self-loops. In some sense, thesemodels are the simplest models of (deadlock-free) systems. Although the expressivity of such systemsis weaker than the expressivity of linear temporal logic, we show that the opacity verification for thesesystems is still hard.
