Design of a Zero Trust Security Architecture for Access Control of the Power Internet of Things

In the context of the development of the power of the Internet, this paper will discuss the problems of open communication between IoT electrical terminals, obfuscation of network protection against electrical boundaries, and the difficulty of accessing IoT terminals through traditional security systems. The paper presents a zero-trust architecture as an IoT terminal access security approach, where the IoT terminal itself becomes the source to establish security authentication and control. Respect access. Security authentication of IoT electrical terminals based on fingerprint mining technology and public key generation algorithm for electrical IoT identification has been completed. Perform continuous monitoring of terminal reliability and effective access control with reliable methods based on terminal performance characteristics. In the case of safe access to the distribution of electrical equipment, the corresponding method is used. Embracing a Zero Trust Architecture is a forward-thinking approach to fortifying the security of the Internet of Things against conventional flooding, packet intrusions, and malicious attacks. This innovative access security method ensures timely detection and swift blocking of potential threats, offering a robust defense mechanism against network assaults targeting the power grid terminals within the realm of the Internet of Things.
