Toward Trustworthy Web Services Coordination

Abstract

In this article, we present an overview of our recent works on enhancing the trustworthiness of Web services coordination for business activities and transactions. The approach is based on what we call application-aware Byzantine fault tolerance. We argue that it is impractical to apply general-purpose Byzantine fault tolerance algorithms for such systems in a straightforward manner. Instead, by exploiting the application semantics, much lighter weight solutions can be designed to enhance intrusion tolerance, and hence the trustworthiness of systems that require Web services coordination.
