Abstract: Our prior work established the decidability of current-location timed opacity (CLTO) in timed automata with integer resets (IRTA). This letter considers initial-location timed opacity (ILTO) ...
Abstract: Critical observability is a property of cyber-physical systems to detect whether the current state belongs to a set of critical states. In safety-critical applications, critical states model ...
A feature-lattice dichotomy theorem mapping each protection-system feature combination to decidable/undecidable and to its exact complexity class. Decidable fragments closed under composition, so that ...
