The Security of Vehicular Networks

Professor J. P. Hubaux, EPFL

Abstract: Vehicular networks are likely to become the most relevant form of mobile ad hoc networks (see e.g. In this talk, we address the security of these networks, a topic that has been (surprisingly) overlooked by the research community. We provide a detailed threat analysis and devise an appropriate security architecture. We also describe some major design decisions still to be made, which in some cases have more than mere technical implications. We provide a set of security protocols; we show that they protect privacy and we analyze their robustness. We also carry out a quantitative assessment of the proposed solution. This work has been carried out in collaboration with Maxim Raya and Imad Aad.
