Design and Realization of an Authentication System Based on PAM
一个基于PAM的身份认证系统的设计与实现

Today people pay more attention to network security. Authentication has become a strong measure to guarantee application security. There are some authentication products at present,most of which have few authentica- tion measures and poor scalability,so it is hard to meet various requirements. An authentication system based on Lin- ux PAM (Pluggable Authentication Modules) is presented in this paper. It can support more authentication measures and has good scalability. In this article,first,PAM is introduced and key issues of using PAM are presented. Second, the authentication system is designed. Finally,an authentication example is given to illustrate the operation principle of the system.
