网络化制造集成平台集中式身份认证策略研究

针对网络化制造集成平台身份认证所面临的问题，提出了一种网络化制造集成平台的集中式身份认证策略。在该策略中，身份认证中心服务器接管各应用系统的认证模块，主要有用户管理、帐号映射管理、身份认证服务和系统管理等功能；采用了基于浏览器／服务器的4层web服务体系结构，构建了其技术实现体系，并对其中的单点登录和注销的实现、信息传输的安全性，以及身份认证服务的性能等问题进行了分析。最后，结合该身份认证策略在网络化制造集成平台中的应用，对其运行效率进行了分析。

Centralized identity authentication strategy in networked manufacturing integrated platform

To deal with the identity authentication in networked manufacturing integration platform, a centralized identity authentication strategy was proposed. According to this strategy, central identity authentication server took over the authentication modules of different application systems, whose functions included user management, account mapping management, identity authentication service, and system management. The architecture adopted four-level Web service framework based on Browser/Server. Furthermore, some key problems, including single-point logging and logout, the safety of information transmission, and the performance of identity authentication service were discussed in detail. Finally, the operation efficiency was proved by the application of the centralized identity authentication strategy in the networked manufacturing integration platform.
