摘　　要：讨论了在Kerberos 5鉴别系统中受限代理的实现和应用问题 为了在网络环境下实现分布式授权和记账机制 ,首先介绍了受限代理模型 ,分析了基于公开密钥和对称密钥机制的鉴别系统实现受限代理的方法 ,特别强调了在Kerberos 5中实现受限代理的相关问题 由于鉴别、授权和记账服务之间存在紧密联系 ,最后将受限代理应用于分布式授权和记账服务中 。The issue of implementation and applicaton of restricted proxy based on Kerberos 5 is discussed in this paper. In order to realize distributed authorization and accounting in nework environment, the model of restricted proxy is introduced first. It is analyzed that the implementation methods of restricted proxy based on authentication system which using public key cryptography and symmetrical key cryptography, and problems to realize proxy in Kerberos 5 and emphasized. As authorization and accounting are closely related to authentication, the restricted proxy is applied in the area of authorization and accounting last, which provides a vehicle for implementing authorization and accounting mechanisms in distributed systems.

关 键 词：Kerberos5 受限代理 分布式授权 记账机制 身份鉴别 公开密钥机制 对称密钥机制
