Research on Role-based Access Control in IPv6 Smart Home

In this paper, we analyze and improve the limitations of the traditional Role-based Access Control (RBAC) model, and we propose an improved RBAC model called ET-RBAC. In ET-RBAC, the constraints of environment module and time module are added to realize dynamic authorization and resource allocation of roles on the basis of the original RBAC model. For the revocation of resources and permissions, the non-relevant revocation method is adopted to avoid the influence of the dynamic changes of the upper-level role on the permissions of the next-level role. We design and implement the ET-RBAC model, including role design, user design, permission design, family group design, resource allocation mechanism design and database management model design, and the model is implemented in the smart home management system. After completing the overall design, this model can be applied to various application platforms with access control requirements to ensure the security of application platform resource access.
