Abstract: As an efficient way to guarantee network security, access authentication has been largely deployed. In order to satisfy the authentication requirements in wireless mobile environment, this paper designs an authentication mechanism based on EAP and Diameter protocol, which can support many authentication method. This authentication mechanism is extensible, and it is easy to manage different authentication processes. This authentication mechanism also performs well in the test environment.

Key words: Authentication mechanism, Extensive authentication protocol(EAP), Diameter

摘要： 对用户进行认证是目前广泛使用的一种保障网络安全的有效手段。为了满足无线移动环境下不同用户的认证需求，文章基于Diameter协议和EAP协议设计了一种支持多种认证方法的认证机制，该认证机制具有良好的易扩展性，并且易于对不同认证过程进行管理。通过应用测试，认证性能良好。
