Edge side equipment trusted access method based on zero-trust architecture

The invention relates to the technical field of electric power internet of things, in particular to an edge side equipment trusted access method based on a zero-trust architecture, which realizes fine-grained access control and authority management, and allows authorized users or equipment to access specific electric power resources and functions. The method mainly comprises the steps of establishing a dynamic access control model, realizing a dynamic access control strategy, performing dynamic access control optimization based on an intelligent algorithm, and designing a security audit mechanism. According to the method, dynamic control over power terminal access is achieved, corresponding dynamic access control strategies are formulated according to various conditions such as identity authentication failure and insufficient authority in the power terminal access process, the safety and stability of a system are guaranteed, the efficiency and accuracy of dynamic access control are improved, a perfect safety
