Package-Role Based Authorization Control Model for Wireless Network Services

摘要

Authorization and authentication services are the major components protecting integrity and authenticity. Authorization control service provides a mechanism to verify user permission to access services. In wireless networks, not only users may change roles but also services can be added, removed or modified more frequently. Although Role-Based Access Control or RBAC can simplify the management of dynamic users, it does not consider dynamic permissions between roles and services. To allow dynamic permission assignment between roles and services, in this paper, we present an authorization control model extended from RBAC using packages. The authorization control is specially designed to achieve optimal cost for large scale and dynamic networks of users and services.
