The Design And Implementation Of Gansu Netcom Portal Platform Based-on Single Sign On

With the development of information technology, the informatization level of all application websites increases constantly. Meanwhile, the information system become more and more popular. So the integration demands among each application web site become more and more intensive. User data which is the foundation of base data and authentication, has become the key element of success for informatization system integration. Therefore this paper implements the Single Sign On System in multi application service environment which is used in user data integration, identity authentication, privilege management and so on.Single Sign On(SSO)refers to that the users only need one time's identity authentication to visit all privileged application. And administrator does not need to modify or interfere with user logging to carry out safety control conveniently. in such a way , a platform used for user unified authentication and user data unified management can be built.The research content comes from the development of The CNCMAX(China Netcom Corporation MAX) platform of Gansu Netcom, it is an one-stop Web entertainment application platform. Combing with the specific requirements, this paper comes up with overall design of CNCMAX, introduces the frame of Single Sign On System. This system is based on ASP.NET and developed with C# language and achieve several goals as following :①According to CNCMAX project requirements, this paper not only implements all kinds of application services of this website and the unified authentication of the Single Sign On system which can solve the repetitive login problem of cross-application in various applications, but also realizes the application system integration in the Single Sign On system.②Design the framework of SSO system. Realize the SSO core logic by using memory management to manage the user data, and realizes a better way to login in, which improves the system performance,the data of the users will be storaged in SQL Server, this is a safe way to protect the data.③According to the rational design, this SSO system can integrate the other applicatons more easily and conveniently with WebService and querystring, which is more advanced than general SSO systems. At present, the system has run on the CNCMAX website of Gansu Netcom successfully and stably. This system allows users to break through the limitations of cross-application in the repeated logins which enhance the experience of the users and improve the development of the CNCMAX platform.
