Current-state opacity formulations in probabilistic finite automata
(2014)A system is said to be current-state opaque if the entrance of the system state to a set of secret states remains opaque (uncertain) to an intruder - at least until the system leaves the set of secret states. This notion ...

Verification of infinite-step opacity and complexity considerations
(2012)We describe and analyze the complexity of verifying the notion of infinite-step opacity in systems that are modeled as non-deterministic finite automata with partial observation on their transitions. Specifically, a system ...
