Fine-grained role-based delegation in presence of the ...
Several role-based delegation models have been proposed in the literature. However, these models consider delegation in presence of the general hierarchy type. Multiple hierarchy types have been proposed in the context of Generalized Temporal Role-based Access Control (GTRBAC) model, where it has been shown that multiple hierarchy semantics is ......
An Organizational Structure-Based Administration Model for ...
There is much research on role-based access control in the enterprise environment [4-7, 11-14]. As we previously mentioned, RBAC is a good access control model for a large organization.
