Purpose – Automated composition of semantic web services has become one of the recent critical issues in today's web environment. Despite the importance of artificial intelligence (AI)-planning techniques for web service composition, previous works in that area do not address security issues, which is the focus of this paper. The purpose of this paper is to(More)
— Cloud computing is a computing paradigm which allows access of computing elements and storages on-demand over the Internet. Virtual Appliances, pre-configured, ready-to-run applications are emerging as a breakthrough technology to solve the complexities of service deployment on Cloud infrastructure.

Currently, most enterprises deploy their services on the Web. This augments the request for tools to perform discovery, selection, composition and invocation of Web services. Among them, Web service discovery should be considered more important. Along with the growing number of available Web services, there is a need for tools not only to perform discovery,(More)
More and more Web based systems are being developed by composing other single or even composite services. This is due to the fact that not all available services are able to satisfy the needs of a user. The process of composing Web services involves discovering the appropriate services, selecting the best services, combining those services together, and(More)
Nowadays, different devices and applications require interconnecting and communicating in convenient manner on the Internet. This can be achieved by Web service technology. Regarding the open and unreliable Internet where Web services applications run over it, security for Web services is a necessity and should be applied to keep service providers and(More)
Nowadays service composition has been received lots of attentions considering the fact that no single service can satisfy users' desires in the majority of service oriented scenarios. In this respects, many enterprises decides to integrate their services and applications to fulfill required goals by service consumers. Despite the importance of Web service(More)
Automated composition of Semantic Web services has become one of the recent critical issues in today's Web environment. Despite the importance of AI-planning techniques for Web service composition, previous works in that area do not address security issues, which is the focus of this paper. Based on our prior work, i.e. AIMO, we present an approach called(More)
