Trusted routing for VANET
Terence Chen, Olivier Mehani, Roksana Boreli · 2009
Trust establishment in VANET is a particularly challenging task due to the lack of infra-structure, openness of wireless links and the usually highly dynamic network topology. To overcome these difficulties, we propose a trusted routing framework that provides message authentication, node-to-node trust and routability verification, without online assistance of Certificate Authorities (CA). Our approach prevents identity impersonation, false link availability indication by compromised nodes as well as some of routing protocol specific misbehaviours. By applying this framework to the Optimised Link State Routing Protocol (OLSR), we demonstrate how this mechanism can be used to establish trusted routes.
