Sso Study, Based On J2ee Broadband Portal

This paper emphatically investigates single signed-on (SSO) technique, which is one of the key technology in ChinaVnet. It involves flow system, theory foundation and idiographic realization plan of "single sign~on> the communication of the whole network" .Firstly, this paper gives a presentation of the topic origin and the characteristic of the internet application; then it also analyses the meaning of SSO technique for construction of integrated internet application system. Having done a lot of research on the SSO solutions currently used in the world and considering of the practical requirement, we presented a SSO solution based on the Cookie technology and Token (UserToken and SPToken) mechanism.We adopted digital sign technology and encryption arithmetic processing to meet the requirement of security and user credibility, on the other hand, We adopted standard XML Web Service access mode to solve the isomerous problems for platform. In addition, we choosed J2EE architecture to develop and deploy our application. This paper offers the SSO flow chart, authentication &verification process and SSO kernel data model.At the end of the paper, we make a summary of the work, and put forward some incomplete problems of this SSO system. The topic of the paper comes from AnHui telecom internet integrate operation system .
