Broker based secure web service composition using star topology

Web service is a mechanism of providing an interoperating communication between different software applications, running on a variety of platforms and frameworks. Web service composition can be processed with the help of Business Process Execution Language (BPEL) and Ontology Based Web Language (OWL). The existing business processes are unable to support human user interaction, authorization, encryption and decryption mechanisms. There is need to introduce secure broker based technique for web service composition. In this paper, we have proposed a broker based framework for securing the web service composition by introducing a broker´s layer between business process and web services. The secure composition of web services will be performed using transposition technique based on star topology and Intalio business process designer. The proposed framework is illustrated with the example of different hotels running in different places in secure manner over the internet. The proposed technique will help to reduce the UDDI load.
