Rewriting Logic Approach to Modeling and Analysis of Client Behavior in Open Systems

Abstract : Requirements of open systems involve constraints on clients behavior as well as system functionalities. Clients are supposed to follow policy rules derived from such constraints. Otherwise, the system as a whole might fall into undesired situations. This paper proposes a framework for system description in which client behavior and policy rules are explicitly separated. The description is encoded in Maude so that advanced analysis techniques such as LTL model-checking are applied to reason about the system properties.
