Application Research Of Uniform Identity Authentication Service In Telecom IT Support System Based On SOA

People now more and more concentrate on EAI -Enterprise Application Integration, but a key obstacle factor is that each bussiness system has their own scattered authentication mode. Before integrate different business system process, you need to solve the problem of the repeated authentication and hidden trouble after integrated. So, how to uniform manager the authentication informating in the heterogeneous enviroment, and built a uniform authentication platform to integrate different authentication technology, as a whole to consider the authentication integration in the enterprise information integration is currently a hot research.At first, this page analyse the recent anthentication technology and products popular at home and abroad, summarize the different applications for different technology and their limitation. And according to the requirement of the research work, In-depth study the SOA, Service-Object Archecture theory, analysis and summarize the popular implementation technology recently, like SOAP, WSDL, UDDI, WS-Security and so on..Secondly, In-depth study how to using SOA to implement the uniform authentication in the enterprise information integration and its heterogeneous environment, focus on how the implement the uniform authentication and how the heterogeneous application system to invoke the authentication service with SOA.Thirdly, according to a real prjoect' s requirement and the goal of building in the telecom corporation, bring up a uniform authentication platform solution based on SOA, provide the case study, solution and code.In-depth study the access token in the authentication step of the uniform authentication platform, bring up the client-store needless access-token mode according the university and safty requirement in authentication step, Effectively improve the university and simplicity and not pay the safety as the cost.At last, point out the issue that the system can further study, and give the authentication technology trend outlook.
