Study on Access Control Model of Service-Oriented Computing

To protect the services against illegal accessing, misusing and tempering is the essential problem in service oriented computing paradigm. SOC relies on the SOA, which is a way of reorganizing software applications and infrastructure into a set of interacting services. Due to loosely coupled and dynamic characteristics of SOC environment, existing access control models and security mechanisms can hardly meet the requirements of security the services in the SOC environment complete, an access control model is proposed in this paper. This paper considers access control to Web-based service that also depends on the strength of identification mechanisms as a context-dependent parameter. Furthermore shows how to model this context-dependent access control by using role-based concepts. By using an BindingContext matching mechanism to support fine-grained access control.
