Access of Power IoT Devices Based on Zero-Trust Technology

With the development of the power IoT(IoT), traditional terminal access technologies struggle to cope with new challenges. This paper explores the application of zero - trust technology to solve the access problem in the power IoT. It analyzes the challenges such as massive device access, complex network environments, and diverse security threats faced by terminal access, as well as the limitations of traditional technologies. It elaborates on the key elements of zero - trust technology, including multi - factor identity authentication, dynamic access authorization, and continuous monitoring and analysis. It also presents linear SVM - based terminal classification and risk identification, and terminal trust evaluation and access control methods. It introduces the application architecture and design of zero - trust technology in the access of the power IoT. Through cases, it compares its advantages over traditional technologies and shows the achievements in improving security performance, equipment management efficiency, and ensuring stable power supply. The conclusion points out that zero - trust technology can enhance the security and reliability of the power IoT, but the issues of cost and compatibility need to be considered during its application.
