本方案在分布式数据资源共享网络建设中实现了多个站点的跨域全局登录、用户认证和用户授权等功能。
This solution plays a vital role in distributed data sharing network construction, which realizes cross domain universal user login, user authentication and user authorization.
经仿真实验和性能分析表明，该模型具有很高的安全性，且在大规模跨域的联合认证时更灵活、轻量及高效。
The model has higher security by emulation experiment and performance analysis, and it is more flexible, lightweight and efficient in the united authentication of large-scale cross-domain.
并采用分布式认证方法，支持用户跨域访问应用服务器，有效实现了多域环境下的单点登录。
The SSO across multiple domain is implemented by means of distributed authentication, so the users can access the application server in different do- main.
支持多认证方式的单点登录是目前的一个新需求，通常这又使认证协议的实现和跨域的认证更加复杂。
The requirement of supporting multiple authentication in single sign-on scheme often complicates the realization of authentication protocol and cross-realm authentication.
