Research And Application Of Supervision And Examination Platform Based On CD-SSO

With the development of Network Technology, all kinds of operating systems based on Network Platform have continuously entered into different businesses, these systems bring great benefits to the users. But because of the network's openness, these systems call for a higher security and ensure the users'legitimately visit to them.This paper analyzed the current situation of Cross Domain SSO and designed the SAML model based on the Pull model and Push model, described its structure and working processes. It will be divided into message delivery, trust services, unite authentication and so on, expounded the detailing and implied the modules. Message delivery module have transported the SOAP message based on SAML token to other modules, analyzed "the second validation" of it, realized the user's safely visit to numerous application systems, given convenience to the users and efficiently improved its work while also enhancing the security of the application system. The trusted services model has provided enough information with the legal authentication route, which will be used the trusted services chain model. Unite Authentication module was the heart of Cross Domain SSO, which managed authentication and implied the user's authentication. Optimized designed and implemented some of the security model to meet the high requirement of security, in comparison of performance with the models before optimization, optimized models perform better.This paper designed and ensured the security of system, implemented the SAML model of Cross Domain SSO in Supervision and Examination Platform. Cross Domain SSO will be used better identity authentication and widely applied its field.
