物联网应用中基于非法接入点的无线拒绝服务攻击研究

Study on the RAP Based Wireless Denial of Service Attacks in IOT Applications

WiFi无线通信技术在物联网应用领域处于重要地位,常见的WiFi物联网终端设备包括无线网络摄像头、智能手机、PDA、平板电脑、笔记本电脑、智能家居网关和工业自动化控制网关等。攻击者可以通过使用非法接入点发送断网指令给WiFi物联网终端,使它们中断正常的数据通信。目前,国内外还没有有效的解决这类问题的方案。本论文研究了基于非法接入点所实施的无线攻击的特点,分析了攻击的基本原理,并为解决这类攻击提出了有效的方案。

WiFi wireless communication technology plays an important role in lntemet of things （ IOT ） applications, and the popular IOT terminal devices include wireless network cameras, smart phones, tablet computers, notebook computers, PDA, smart home gateway and industrial automation control gateway etc.. An attacker can use a rogue access point （ RAP ） for sending faked deauthentication or disassociation frames to terminate the data communication of the legitimate WiFi lOT ten,final devices. At present, there are no effective solutions to resolve the RAP based DoS attacks. This paper studies the characteristics of the RAP based wireless DoS attack, analyzes the attack mechanisms, and provides a possible solution to prevent this kind of attack.
