Abstract

The Internet of Things (IoT) is a fast growing industry with strong footholds in the smart home market featuring devices such as the Amazon Echo, Ring security cameras, smart TVs, and much more. However, it doesn’t stop there; the industrial sector has begun using smart devices for measurement, automated tasks, and time sensitive communication. Many of these devices have become reliant on WiFi technology and are vulnerable to attacks on the security of the protocols involved.

In this paper, we discuss the details of the deauthentication attack on WPA and WPA2 systems and propose a solution for detection and recovery in IoT networks all included in a single, easy-install device. We evaluated our solution in a smart home environment against variations in packet reception rate, and concluded that our system is e↵ective for small smart home networks. In addition, this solution can be modified in a variety of ways to further the field of IoT security and provide manufactureable, easily accessible smart system security solutions.
