WLAN环境下拒绝服务攻击问题研究

Research of DoS Attack in WLAN

文章探讨了WLAN环境下的拒绝服务(DoS,Denial of Service)攻击问题,提出了一种通过修改短帧隙(SIFS,Short Inter Frame Space)进行DoS攻击的方法,实验表明这种攻击具有较高的攻击效率。同时,对最近出现的一种针对物理层的攻击进行了具体的实验,分析了其攻击机理及危害程度。最后,结合现有协议提出了一些解决方案及安全建议,用以增强无线局域网抵抗攻击的能力。

In this article we have discussed deny of service（DoS） attacks in the environment of wireless LAN（WLAN） and proposed a novel attack method by modifying the short inter-frame space（SIFS）.It is shown that the proposed method is effective in attacking.We have also analyzed the scheme of an emerging attack method aimed at the physical layer and investigated its potentia! damage by experiment.In the last we have given some solutions and advices on how to enhance the ability of the WLAN in resisting attacks based on the existing protocols.
