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 is very important in the field of IoT applications. Common WiFi IoT terminal devices include wireless webcams, smartphones, PDAs, tablets, laptops, smart home gateway and industrial automation control gateways. An attacker could send a disconnection instruction to a WiFi Internet of Things terminal by using an illegal access point, causing them to interrupt normal data communications. At present, there are no effective solutions to these problems at home and abroad. This thesis studies the characteristics of the wireless attacks based on the illegal access points, analyzes the basic principles of the attacks, and proposes an effective solution to the attacks.
