Vehicular communications (VCs) and vehicular ad hoc networks (VANETs) lie at the core of several on-going industry and academic research initiatives. Vehicles and roadside infrastructure units equipped with sensors, computers, and wireless transceivers enable a range of applications that enhance transportation safety and efficiency. VCs offer a rich set of tools but also make possible a formidable set of abuses. For example, an adversary could 'contaminate' large portions of the VANET with false information; or, intercept vehicle-originating messages, track the vehicles locations and transactions, and infer sensitive information about their passengers. Without security mechanisms, VCs can make antisocial and criminal behavior easy, essentially jeopardizing the benefits of deploying VCs systems.
In this talk, we discuss this new and uniquely constrained problem: how to secure vehicular communications. First, we discuss design principles and requirements as well as elements of a secure VCs architecture. Then, we present mechanisms to enhance privacy yet provide strong security; evict misbehaving or faulty nodes; and, extend the traditional notion of trust to data-centric trust, that is, attribute trustworthiness to node-reported data per se. The presented results reflect recent work, jointly with researchers of the Univ. of Maryland, the Pol. of Torino, and the SeVeCom and Car-2-Car communication consortia.
