Web services technologies enable flexible and dynamic interoperation of autonomous
software and information systems. A central challenge is the development of modeling …

Abstract Model checking is a formal verification technique. It takes an exhaustively strategy
to check hardware circuits and network protocols against desired properties. Having been …

Abstract This paper presents Web Service Analysis Tool (WSAT), a tool for analyzing and
verifying composite web service designs, with the state of the art model checking …

We present a framework for analyzing interactions among Web services that communicate
with asynchronous messages. We model the interactions among the peers participating in a …

WS-BPEL applications are a kind of service-oriented application. They use XPath
extensively to integrate loosely-coupled workflow steps. However, XPath may extract wrong …

The Web Services Business Process Execution Language (BPEL for short) is a recently
developed language that is used to specify compositions of web services. In the last few …

Business process integration and automation are among the most significant factors driving
the information technology industry today. In addressing the manifold technology challenges …

A promising way to model the global behavior of a Web Service composition is to
characterize the set of conversations among the participating Web Services. A conversation …

Most works that extend workflow validation beyond syntactical checking consider constraints
on the sequence of messages exchanged between services. These constraints are …

The verification of access controls is essential for providing secure systems. Model checking
is an automated technique used for verifying finite state machines. The properties to be …
