Abstract

The invention discloses an Internet of Things communication traffic analysis method based on Android VPNService, relates to the technical field of Internet of Things security, and mainly aims to solvethe problem that security vulnerabilities of specific implementation of communication protocols cannot be analyzed. The analysis method comprises the following steps: CA root certificate installation: installing and creating a CA root certificate on an Android mobile phone end; Acquiring communication data of the intelligent application; Preprocessing the communication data packet; Establishing alocal server and a communication client; Forwarding, encryption and decryption: forwarding, encrypting and decrypting the data traffic of the unique session process of the intelligent application byusing the local server and the client; And storing and visualizing the communication data. The method is deployed at an Android mobile phone end, no root or other hardware support is needed, the operation is convenient, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of Internet of Things security, in particular to a method for analyzing communication traffic of the Internet of Things based on Android VPNService. Background technique [0002] With the popularization and development of Internet of Things technology, home appliances, street lamps, cars and other devices are connected to smart phones, and these devices communicate with each other, which greatly facilitates people's lives. However, attacks against IoT devices are also emerging in an endless stream. Attackers can steal user privacy and even hijack users’ IoT devices by exploiting flaws in communication protocols, vulnerabilities in device firmware, and improper configuration of smart applications in users’ mobile phones. The threats to the security of the Internet of Things are becoming more and more extensive and serious. Therefore, how to ensure data security and user privacy in the Internet of Things throu...
