Design And Realization Of The Unified Application Portal System Based On Single Sign-on

With the development of the network information technology and the increasing applications of information technology on labor security, more and more systems have been built. But limited by building period, function emphasis, design method and development technology, systems are mostly isolated. So each system has an independent database on user information and a set of user authentication, such as the design of organization and role access, identity authentication and resource access control mechanism typically, not only resulted in raising the possibility of a mistake but reducing the system security. Aiming at soling the problem, we have built the unified application portal system based on SSO (Single Sign-On). Various systems and data resource of labor security have been integrated to the portal system, though the technology of once single identity is authenticated on the firstly access, all authorized resources are allowed to seamlessly access based on the SSO technology, to improve working efficiency and system security and reduce expenses on network.The thesis analyzed the multi-system problems first, explained the necessity and importance of building the unified application portal system based on SSO. Then compared and analyzed the characteristics of several SSO technologies, summarized the advantages and disadvantages of each, as well as the application of environmental, and studied other related implementation techniques. The thesis depicts the solution and technology of the integrated in C/S, B/S systems on original systems' users, groups, organizations, roles and authorities to accomplish unified user management, with the token-based SSO technology. We use UML, JSP, Struts, Spring and Hibernate to realize cross domain and loose coupled system.
