متن کاملIsabelle/Circus
The Circus specification language combines elements for complex data and behavior specifications, using an integration of Z and CSP with a refinement calculus. Its semantics is based on Hoare and He’s unifying theories of programming (UTP). Isabelle/Circus is a formalization of the UTP and the Circus language in Isabelle/HOL. It contains proof rules and tactic support that allows for proofs of ...

متن کاملConfidentiality Annotations for Circus
This paper presents a novel construct for specifying confidentiality properties over Circus processes. By extending the semantics of Circus, we identify how functionality and secrecy can be united within a single framework. We use this construct to formalise a selection of confidentiality properties over a model of an auction system.
متن کاملFrom Circus to JCSP
Circus is a combination of Z, CSP, and Morgan’s refinement calculus; it has an associated refinement strategy that supports the development of reactive programs. In this work, we present rules to translate Circus programs to Java programs that use JCSP, a library that implements CSP constructs. These rules can be used as a complement to the Circus algebraic refinement technique, or as a guideli...
