Prototype for design-time secure and trustworthy service composition

Service-oriented environments provide the opportunity for services from different providers to work together, forming new composite services via composition of existing services. However, in addition to the intended outcomes, composition also introduces the potential for unexpected or emergent behaviour, resulting in new uncertainties, especially in the area of security. Funded by the European FP7 programme, our research focusses on providing a service composition platform that is secure and trustworthy. We will demonstrate the design-time prototype that show how to create service compositions, verify them against security policies and make sensible recommendations based on a user's security preferences.
