Trusted Routing for VANET

Trust establishment in VANET is a particularly challenging task due to the lack of infrastructure, openness of wireless links and the usually highly dynamic network topology. To overcome these difficulties, the authors propose a trusted routing framework that provides message authentication, node-to-node trust and routability verification, without online assistance of Certificate Authorities (CA). They approach prevents identity impersonation, false link availability indication by compromised nodes as well as some of routing protocol specific misbehaviours.
