摘　　要：当前的许多身份认证产品,不更改代码则无法实现新的认证方法,很难满足不同应用系统的要求。文章提出了一种基于PAM身份认证方法,并通过该方法设计实现了一套认证系统,可以针对不同的服务提供不同的认证方法,提高该系统认证的灵活性;对整个传输过程中的数据进行加密操作,有效提高系统的安全性能;在系统中加入了日志管理模块,为以后的维护操作提供了依据。At present, many authentication products are unable to implement new authentication methods without changing their codes, so they are hard to meet various requirements of different systems. This paper proposes an authentication method based on pluggable authentication modules（PAM）,and a certification system is designed and implemented by the authentication method. It can provide different methods of authentication for different services, which effectively enhances the flexibility of the certification system. And the encryption operation is conducted on the data in the transmission process, which effectively improves the system＇s security. With added management log modules to the system, it provides a basis for future maintenance operations.
