无线网络接入认证技术及攻击方法研究

Study on Attacking Methods and Authentication Technology of Wireless Network

概述了无线网络区别于有线网络的属性结构,依据无线网络自身所具有的特点,描述了无线网络所使用的一般的认证框架和技术特点,列出了针对认证过程的常见的攻击技术,同时提出了利用分析无线网络认证协议的脆弱性来设计攻击过程和方法。针对应用最为广泛的全球移动通讯系统(Global System for Mobile Communications,GSM)的认证协议,进行了脆弱性分析,提出了若干种针对认证过程的攻击方式。

The paper describes the attribute structure of wireless network differing from that of wired network.Based on the features of wireless network,this paper introduces the general authentication framework and technology of wireless network.Common attack technologies in the process of authentication are listed.The attacking process and methods are designed by using the vulnerability of wireless network authentication protocol.At last,aiming at widely applicable GSM system,the authentication protocol＇s vulnerability analysis are carried out.Different kinds of attacking mode aiming at authentication process are put forward.
