A Hierarchical Virtual Role Assignment for Negotiation-Based RBAC Scheme

In recent years, user populations of applications systems have been extended the challenge of controlling access to resources using security policies have grown. However, the typical access control technologies and schemes are insufficient to cope with such applications that allow accessing services via huge users or groups. Therefore, the hierarchical virtual role assignment for negotiation-based RBAC scheme is proposed in this paper. It could manage not only one resource server or agent, but also multiple resources servers or agents on the same time via negotiating and supporting by lots of multiple cooperation resources servers or agents. Moreover, it provides an establishment of the efficient user hierarchy structure which allows huge users in a hierarchy will be a highly powerful solution. Therefore, the innovative research and design of the hierarchical virtual role assignment for negotiation-based RBAC (Role-based Access Control) scheme is proposed in this paper, which focus on easily designing the hierarchy role assignment scheme with both extendable and flexible for RBAC model.
