| 摘 要： | 文章提出了一种基于ＰＫＩ的网络安全模型，旨在为网络服务提供有效认证、访问控制、授权、传输机密性、不可否认性等安全机制。该模型在 ＰＫＩ的基础上，结合了 Ｋｅｒｂｅｒｏｓ的优势，并扩展了其机制中服务票据的思想，提出了由授权服务器签名的授权证书的概念，以保证自治式与集中式访问控制相结合的安全管理模式。

| Abstract: | This paper presents one PKL-based network security model to proffer effective security mechanisms inbasis of the PKI,this model takes advantage Of the Kerberos protocol and extends the application ticket in its implementation mechanism. Therefore, it puts forward the concept of the authority-server-signed authorization certificate so as to ensure the security management mode with the combination of the autonomous access control as well as the centralized one. |
