There are difficulties in applying role-based dynamic delegation to Web services. This is because XACML, which is a standard language for describing the access policies of Web services, does not support the dynamic delegation between roles in different domains. We propose role attributes to specify the characteristics of roles in different domains to support role-based dynamic delegation in a Web services system, which services in different administrative domains work together. The proposed method enables the dynamic delegation in a service-oriented system based on the proposed role attributes. Experimental results show that the proposed method performs better than previous methods, resulting in enhancing an authorization rate about 32 percent on average.
