WiMAX认证方案研究

WiMAX安全要实现两大目标:一是为整个无线网络提供机密性保护;二是提供网络接入控制功能。IEEE802.16的安全子层采用了认证客户端/服务器密钥管理协议,在该协议中基站(即服务器)能够对分发给客户端SS的密钥进行控制。本文首先分析了WiMAX网络物理层和MAC层面临的安全威胁,然后给出了WiMAX网络安全体系架构。最后,对散列消息认证码(HMAC)、X.509证书和可扩展认证协议(EAP)进行了详细的介绍。

Research on the Authentication Scheme of WiMAX

WiMAX security has two goals,one is to provide privacy across the wireless network and the other is to provide access control to the network. The security sublayer of IEEE 802.16 employs an authenticated client/server key management protocol in which the BS,the server,controls the distribution of keying material to the client SS. This paper analyzes the physical layer threat and MAC layer threat of WiMAX,then proposes the security architecture of WiMAX. In conclusion,we introduce the HMAC protocol,X.509 certificate and EAP protocol in detail.
