摘　　要：提出了基于无线局域网和3G互联网络的接入认证协议.该协议对无线局域网访问网络的身份进行验证,抵御了恶意访问点的重定向攻击行为,采用对3G移动用户的局部化认证机制和基于快速签名的离线计费方法,有效地提高了重认证过程的效率.仿真结果表明,该协议的平均消息传输延时相对于扩展认证密钥协商协议缩短了大约45%,利用该协议3G移动用户可以在无线局域网网络中平滑地漫游和切换.A new authentication protocol based on 3G-WLAN interworking networks is proposed. It verifies the identity of the WLAN access network to prevent the malicious AP from the re-direction attack, and improves the efficiency of the reauthentication process by using localized authentication mechanisms for 3G mobile subscribers and offline accounting methods based on the fast signature. Simulation results show that the average message transmission delay of the proposed protocol is shortened about 45% of EAP-AKA, and the proposed protocol can provide smooth roam and handover for 3G mobile subscribers in WLAN.
