Weak bisimilarity is one of the most studied behavioural equivalences. This equivalence is undecidable for pushdown processes (PDA), process algebras (PA), and multiset automata (...
Abstract. We consider a formalisation of a notion of observer (or intruder) theories, commonly used in symbolic analysis of security protocols. An observer theory describes the kno...
A notion of open bisimulation is proposed for the Applied Pi Calculus, which extends -calculus in order to facilitate analyzing security protocols. Our notion is based on the label...
