Secured Geographic Routing Protocol for Vehicular Ad Hoc Networks (VANETs)

Résumé

A Vehicular ad hoc network called VANETs is a mobile network allowing to vehicles to communicate with each other in the absence of fixed infrastructure, with the aim of improving road safety through the exchange of alerts between neighborhood vehicles or to offer new comfort services to road users. The characteristics of these networks such as: shared wireless medium and the highly dynamic network topology pose a number of nontrivial challenges to security design. In these networks each vehicle coordinates with every other vehicle in forwarding their packets to reach the destination. Since these vehicles operate in a physically insecure environment; they are vulnerable to different types of attacks such as the blackhole attack, Sybil attack, selective forwarding and altering routing information. This paper proposes a security solution for VANETs using a pre-existing routing protocol Greedy Perimeter Stateless routing. In this solution, each node in a network has a list of its neighbor nodes including a shared secret key which is obtained by executing a key agreement Diffie Hellman, this key will be used by the AES symmetric encryption algorithm to generate a digital signature, after applying the MD5 hashing algorithm on the non-modifiable data of GPSR packets. Our idea consists that each vehicle verifies the integrity and authenticates the sender in the process of route discovery, Comparing with other recently proposed security routing protocols, our security solution needs less computation times in routing transactions because it use AES and does not need any centralized element in vehicular ad-hoc networks.
