Abstract. In this paper we discuss the role of labels in transition systems with regard to bisimilarity and model checking problems. We suggest a general reduction from labelled tr...
We have designed and implemented a general and powerful distributed authentication framework based on higher-order logic. Authentication frameworks — including Taos, SPKI, SDSI,...
This paper formalizes the folklore result that strongly-typed applets are more secure than untyped ones. We formulate and prove several security properties that all well-typed app...
Abstract. We summarize and reorganize some of the last decade's research on real-time extensions of temporal logic. Our main focus is on tableau constructions for model checki...
In summary, RDL is an intuitionistic temporal logic for the specification of requirements and design of time-dependent systems. Coverage of RDL includes a backward chaining theore...
