Fine-Grained Access Control Mechanism of Energy Internet

The Energy Internet has generated huge amounts of information on the production devices,transmission devices,and energy consumption devices.The leakage of data in the collection,transmission,and storage process will cause serious security problems.The existing Energy Internet security methods rely on traditional 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 access 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 security status of the environment in real time.Experimental results show that the access control model can safely and accurately execute access decisions in the Energy Internet scenario,and the processing performance is more stable.
