As an emerging technology derived from the Internet of Things, smart home is also a typical information physics fusion system. In recent years, the smart home market has experienced rapid growth, and related research has pointed out many security privacy issues in the field. Our research is centered on the Samsung SmartThings platform. This paper especially studies the side channel estimation technology of smart home wireless traffic. Different from the traditional method, we use this speculation technology to design and implement an abnormal behavior detection system for smart home applications, called SmartDetector. The system speculates on currently active applications by utilizing side channel information in a smart home wireless network. Further, by comparing with the expected application behavior extracted from the source code or the user interface, SmartDetector can effectively detect anomalies that may exist in the interaction between the application and the smart device. To evaluate the effectiveness of the SmartDetector, we analyzed 181 officially available applications and conducted an experimental evaluation of 60 applications with anomalous behavior based on this development. These exceptions have attacks on smart devices such as unauthorized access or event spoofing. The experimental results show that SmartDetector can effectively verify the working logic of the application in the smart home platform and has high accuracy in detecting abnormal behavior of the application.
