Towards Dynamic Cooperation of e-Services with Security Based on Trusted Right Delegation

摘要

With the rapid development of e-Service market, a large number of e-Services, for example, stock trading, real-time traffic report, or travel planning, are already available on the Web. In order to achieve the complex business requirement using e-Services, there has been a growing interest in e-Services composition and cooperation. In order to make effective utilization of Internet resources, it is a trend to enable the e-Services to be dynamically deployed and executed for composition and cooperation. This paper will focus on security issues in dynamic composition and cooperation of e-Services. With the extended WSDL description and through the replication technique, the replica of an e-Service can be dynamically deployed and executed on the optimum server, which is selected from the registered servers in the enhanced UDDI center. And, a security mechanism of trusted right delegation is introduced to ensure the safely and dynamically sharing of the resources among the e-Services.
