A formal role-based access control model for security ...
The presented security policy model supports the specification of Role-Based Access Control (RBAC) policies with role hierarchy, object type hierarchy and role mapping in a multi-domain setting. We define a formal model for network state related to locations and provide the mapping of actions to the formal model....
Constructing RBAC Based Security Model in u-Healthcare ...
It is possible to construct a security policy for each enterprise using an RBAC. The basic concepts of role-based access control consist of user (U), role (R), sessions (S), and permission (P) . In addition, role hierarchy, constraints, and privacy purpose group are included.
An analysis of graphs that represent a role-based ...
Abstract. The present work considers structural modification of the role hierarchy in a formal model of the role-based access control. The marked directed graph (the role graph), graphically representing an ordered set of roles, was analyzed to define the ordering relation in the role set and to distribute permissions according to the generated hierarchy....

The latest role-based access control (RBAC) standard is also highlighted. This unique technical reference is designed for security software developers and other security professionals as a resource for setting scopes of implementations with respect to the formal models of access control systems....
Context-Dependent Access Control for Web-Based ...
Furthermore, we show how to model this kind of context-dependent access control for web-based collaboration environments by using role-based concepts. Additionally, we present how complex role hierarchies in the context-dependent case can be generated from basic role hierarchies....
