Abstract: With the advent of digital economy era, the application of IoT (Internet of things) is developing rapidly, and is penetrating into all aspects of people's production and life. While IoT brings us convenience, its equipment, network and application are also facing severe security challenges. This paper firstly analyzes the security threats faced by all levels of IoT in digital economy era, and uses SE and its characteristics to propose a security protection mechanism based on SE(Security Element) , which can build a one-stop cloud-to-end overall security solution from the system architecture level to solve the shortcomings and loopholes of the current IoT business. Applying this security mechanism to the field of e-government can solve the security problems of the mobile end, and achieve the goal of high security, high convenience, low cost, reproducibility and popularity of the mobile end.
