Abstract: Owing to the application (APP) software for the mobile users are more and more increasing, there are various attacks or challenges appeared in accessing control of the cooperative multiple servers. However, the typical access control schemes are insufficient to deal with the kind of applications that allow accessing services by way of huge users or groups. Hence, we propose the cooperative RBAC (Role-based Access Control) scheme with negotiation-based hierarchical virtual role in this paper. It could manage not only one resource agent server, but also more than one multiple agent servers on the cooperation domain through negotiated virtual role or role set to access the collaboration agent servers. Furthermore, it provides a hierarchical virtual role structure allowing flexible negotiations among the multiple agent servers in this cooperation domain. Because of concentrating on easily designing the negotiation role approach with both extendable and flexible for RBAC model, it is a highly powerful solution using the innovative research and design of the hierarchical virtual role assignment for negotiation-based RBAC scheme.
