Design and implementation of unified authentication system on cookie

Based on fully understanding of principle and process of cookie-based authentication,a single sign-on authentication method is provided,which use the technology of cookie redundancy to slove authentication on cross-domains.It completes the single sign-on and unified authentication among sub-systems by visiting the trusted-domain list and transfering shared cookie information.It is applied to design a comprehensive information service platform system on tobacco intellectual property.The process of key modules are presented, which consist of the safety design for cookies,identity authentication and unified authentication.At last,the result of experiments are given to show that the method provided is simple and practical,it can resolve the single sign-on and safe authentication among sub-systems.
