功能扩展的认证中心服务器模型的研发

Research and Development of Extended CA Server Model

作为IPsec协议基础之一的认证中心(CA),已在VPN中得到了广泛的应用。通过研究VPN网络中经典CA服务器的功能和不足,提出了一个功能和管理方式有所改进的,更能满足大型VPN系统需要的CA服务器模型,并对其进行分析,提出了其实现的数据源码。

CA has been widely used in VPN as one of the basic elements of IPsec protocol. The paper put forward an extend ed CA server model which could better satisfy the large VPN system＇s need by studying the function and deficiency of the typi cal CA used in VPN. Then it analysed the extended CA model and finally put forward its source-date code.
