It is important to have multi-agent robotic system specifications that ensure correctness properties of safety and liveness. As these systems have concurrency, and often have dynamic environment, the formal specification and verification of these systems along with step-wise refinement from abstract to concrete concepts play a major role in system correctness. Formal verification is used for ex...

A mix network achieving strong correctness and privacy is proposed. The degree of correctness and privacy are precisely stated and a formal proof of correctness is given. A grouping function is employed to achieve stronger correctness and higher efficiency without compromising strong privacy. In order to further improve the efficiency of the mix network a new batch verification technique, suita...

This paper aims to raise the level of verification challenges by presenting a collection of sequential Java programs with correctness annotations formulated in JML. The emphasis lies more on the underlying semantical issues than on verification.

The traditional approach for establishing the correctness of group communication protocols is through rigorous arguments. While this is a valid approach, the likelihood of subtle errors in the design and implementation of such complex distributed protocols is not negligible. The use of formal verification methods has been widely advocated to instill confidence in the correctness of protocols. I...

Web service compositions (WS compositions) coordinate Web services of different enterprises. They are expected to constitute the foundation of service-oriented architectures, to improve business processes as well as to foster intraand inter-organizational integration. Especially in inter-organizational contexts, quality of service referring to non-functional requirements and conformance to func...

Ensuring the functional correctness of hardware early in the design cycle is crucial for both economic and methodological reasons. However, current verification techniques are inadequate for industrial designs. Formal verification techniques are exhaustive but do not scale; partial verification techniques based on simulation scale well but are not exhaustive. This paper discusses promising appr...

Workflow management technology has become a key means to improve enterprise productivity. More and more workflow systems are crossing organizational boundaries may involve multiple interacting organizations. This article focuses on type of loosely coupled architecture with collaborative tasks, i.e., each business partner owns its private process is able operate independently, all involved organ...

Formal verification of process models is an important issue in Business Process Management. Such a verification provides the information about the correctness of a process model, can be also used for checking business compliance or as a preliminary step to simulation. In this paper, we provide an overview of the existing tools for such a verification.
