For access control policy composition problem of composite services in Web services multi-domain environment,the attribute based Web services access control policy description framework was proposed and the services access control policies were formally expressed with atomic attribute value constraint.After analyzing the control structures in services composition description document,combining the access control policy composition operators with access control policy rule composition operation,the composite Web services access control policies composition method was designed to compose the composite service access control policies.Finally,the Web services access control policy composition process was given and the practicability of composition method was verified through a case.
