Role-Based Access Control for Vehicular Adhoc Networks

Abstract

VANET, the vehicular ad-hoc network, is a new communication technology that is characterized by a large amount of moving hosts, dynamic topology, and permanently changing data flows. VANE T specific features result in poor access control and isolation of sensitive data in intranetwork. Our paper discusses this issue and adapts the role-based access control to VANET with a hierarchy of objects and roles to ensure access control and improve data confidentiality.
