“…The static mapping is a tightly coupled and global role mapping approach with a coordination center [7]. The static role mapping has advantages in large-scale distributed intra-domain policy synthesis, but in less highly interactive conditions.…”

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.

“…Bertino et al [16] projected the temporal RBAC (TRBAC) model that allows and disallows a role at run time according to requests of users. In [17], in some applications, certain roles need to be constant and stay enabled all the time, while there only the users and permissions that are going to be assigned dynamically. Another generalized model is also projected called TRBAC model that look for activation of role instead of role enabling.…”

There has been a growing trend to use the cloud for largescale data storage. It has raised the important security issue of controlling and preventing any unauthorized access of data stored in the cloud. The role-based access control (RBAC) one of the well known access control model provides flexible controls and management by providing two mappings, one by mapping users to the roles and another by roles to the privileges on the data objects. In this we will discuss a rolebased encryption (RBE) scheme that has been used previously with RBAC. A hybrid cloud storage of the RBE scheme architecture permits an organization to store data secure in a public cloud and maintains the private information related to the organizational structure in a private cloud. In this we will also focus on the models that are available in cloud computing. General Terms Cloud Computing KeywordsRole Based Access Control (RBAC), Role Based Encryption (RBE). Access Control Models, Attribute-based Encryption Model, Multi-tenancy Model.

“…In [12], the authors argue that in some applications, certain roles need to be static and stay enabled all the time, while it is only the users and permissions that are dynamically assigned. In this context, they proposed a generalized TRBAC (GTRBAC) model that advocates for role activation instead of role enabling.…”
