摘　　要：随着计算机网络的发展,网络安全问题已变得日益重要,而身份认证在安全系统中的地位极其关键,是最基本的安全服务。Kerberos协议是基于私钥密码系统的身份认证协议。文中首先对Kerberos协议的认证原理进行分析;然后基于公钥体制的加密技术和Kerberos协议,提出了一个安全性更高的身份认证协议;最后分析了两种协议的异同。With the development of computer network, the problem of network security is becoming even more important. Authentication is very important and basic security service among the security systems. Kerberos protocol is an authentication protocol based on private key cryptosystem. In this paper, first, the authentication theory of Kerberos protocol is analyzed, then based on the Kerberos protocol and public key eneryption system,a higher security of identity authentication protocol is designed. Last analyzed the differences between the two protocols.
