Improved detection of malicious modifications

Abstract

Vehicular Ad-Hoc Networks (VANETs) are special forms of Mobile Ad-Hoc Networks (MANETs) that allows vehicles to communicate together in the absence of fixed infrastructure.In this type of network beaconing is the means used to discover the nodes in its eighborhood.For routing protocol successful delivery of beacons containing speed, direction and position of a car is extremely important.Otherwise, routing information should not be modified/manipulated during transmission without detection, in order to ensure the routing information, messages must be signed and provided with a certificate to attest valid network participants. In this work we present a beaconing protocol with key exchange to prepare the generation of a signature to protect the routing information protocol 'Greedy Perimeter Stateless Routing'.
