Research And Design Of Single Sign-On System Based On SOA

The basic philosophy of Single Sign-On(SSO) is to provide unlimited accessing with single sign-on. With the continuous development of Internet technology, Internet applications continuous increase, often work together to complete in a number of Web applications. SSO can simplify user's operations, advance user's experience, reduce the cost of development and management. As a result, SSO has become the hot spot of research security field internally or abroad.The common technology of SSO is analyzed and researched, through analysis of Cookie, Session and IP technology, ticket of single sign-on system of Web-based applications is researched gradually. Through indepth analysis of a variety of SSO system models, research and bring forward an active or passive broker-based SSO system program and the agent-based SSO system program of using Session sharing technology. Through the comparison and analysis of these three programs, the advantages of Session sharing technology in the SSO system application is clearly defined .Applying the Session sharing technology in SSO is a novel method, it is particularly suitable for research and development of SSO system on a variety of different types of Web applications. Basing on the analysis of the existing Web applications, an original form of the SSO system of Fujian University of Technology is implemented to use Session sharing technology.The reality shows that the SSO system which uses Session sharing technology can minimize the amount of modification in Web application system software, have safe and reliable characteristicsso.
