Access Control Model for Composite Web Services

摘要：

　　With enterprises increasingly depending on Web services to build complex information systems,security problems especially the services access control problems are becoming serious issues.For the cross-domain,dynamic,fine-grained requirements of composite services access control in Web services multi-domain environment,we propose a composite Web services access control model combining the idea of attribute based access control.Then,elements and relations among elements in our model are formally described.In our model,composite Web services access control policies can be composed according to the relations of services composition and access control policies of component Web services.The access control for services parameters,single Web services and composite Web services are all supported in our model.We have implemented a prototype of our model and put forward the work process of our model.Finally,the advantages over traditional access control models are showed by analyzing characteristics of our model.
