Web services composition is the main concern of application integration and on-demand businesses. However the barriers of the security domains impede the interoperability and composition of services. In this paper, we introduce the access control model for Web service composition(ACM4WSC 1 ). Based on this model, the users can access the composite Web service without concerning the access control of elementary services. We present two methods to manage the access control policies of the elementary services. Then we compare the two methods and point out their features.
