UDDI Access Control for Virtual Enterprise
基于虚拟企业的UDDI访问控制研究*

UDDI is the key technology of Web service system, which enables the business entities to share information and discover each other; thus it become the foundation of E-business. However, the access control methods in UDDI are not so enough in actual applications. Aiming at the business needs of virtual enterprises, we point out the shortage of UDDI access control and propose a role-based access control scheme. For the ease of configuration and maintenance, we use the existing XML-based access control specifications XACML to implement the UDDI access control mechanism in virtual enterprise.
