一种改进的WLAN-3G融合网络认证协议

Improved Authentication Protocol for WLAN-3G Interworking Networks

本文在分析了现有3GPP WLAN-3G融合网络接入认证协议EAP-AKA的优势和不足的基础上,引入WAPI证书鉴别机制,提出WAPI-3G互联结构模型,并针对该互联模型设计了一种接入认证协议EAP-WAPI.本文提议的WLAN-3G互联结构模型及接入认证机制解决了融合组网环境下WLAN终端统一接入认证的问题.分析和仿真结果表明,相比于原有的WAPI认证协议WAPI-XG1,本文所提议的协议具有较高的安全性和执行效率.

Based on analyzes the available WLAN-3G interworking protocol EAP-AKA proposed by 3GPP, introducing the certificate authentication mechanism, an improved architecture and a novel authentication protocol EAP-WAP1 are proposed in order to achieve authentication for the users using WLAN access network, which solves the problem of integrated access authentication. The analysis and simulation results show that compared to the formal WAPI authentication protocol WAPI-XG1, the protocol EAP- WAPI improves the process of authentication interaction and the implementation efficiency.
