T-RBAC based Multi-domain Access Control Method in Cloud
نویسندگان
چکیده
Access control technology protects the cloud from being accessed illegally. However, traditional access control method cannot meet the new demands of the cloud environment. In order to improve the deficiency of the current multi domain access control method in timeliness and flexibility. This paper puts forward a dynamic access control policy on the basis of task driving mechanism. The new method combines the advantage of RBAC and task driving mechanism, introduces in limit aging and real time strategy synthesis. Comparative trials show that the new policy had an advantage in flexibility and availability of multi-domain access control model.

متن کاملA Novel Role-based Access Control Model in Cloud Environments
In Cloud environments, the relationship between resources and users is more ad hoc and dynamic. The role-based access control (RBAC) model is an appropriate access control model for Cloud environments. When using the RBAC model in Cloud environments, some new elements should be considered. This paper proposes a SAT-RBAC model (security and availability based trust relationship in RBAC) and adop...
