A Two-Level Authentication Protocol for Vehicular Adhoc Networks

The technology growth nowadays has made its way into the world of transportation by establishing smart vehicles and smarter vehicular transportation named Vehicular Ad-hoc networks (VANET). VANET gains its fame day by day by the way how it facilitates the efficient and safe transportation to the voyagers. However, the prime requirement of VANET is authentication. The main aim of the proposed work is to develop a practical and efficient pseudonymous authentication protocol which augments the conditional privacy preservation. Two-Way authentication is provided using local alias and global alias name. The alias name has offered to all the vehicles who register with the certification authority. The simulation result shows that the Two-Way protocol provides authentication with optimal packet delivery ratio (PDR), end-to-end delay and propagation delay.
