The Energy Internet has generated huge amounts of in-formation on the production devices,transmission devices,and en-ergy consumption devices.The leakage of data in the collection,transmission,and storage process will cause serious security prob-lems.The existing Energy Internet security methods rely on tradi-tional access control mechanisms and specific network boundary defense mechanisms,which has the limitations of static strategies and coarse design.We combine the advantages of role-based ac-cess control(RBAC)and attribute-based access control(ABAC),and propose a trusted Energy Internet fine-grained access control model based on devices'attribute and users'roles.We have not only achieved fine-grained Energy Internet resource allocation,but also ensured that the access control process is related to the se-curity status of the environment in real time.Experimental results show that the access control model can safely and accurately ex-ecute access decisions in the Energy Internet scenario,and the pro-cessing performance is more stable.
