A survey of authentication schemes for vehicular ad hoc networks
Vehicular ad hoc networks (VANETs) are planned to be deployed within the next decade to improve driver safety, prevent collisions, and provide traffic optimization. Recent years have witnessed an increasing interest in the security schemes for VANETs as this area was relatively less explored compared to other areas such as medium access and routing. In particular, efficient authentication of the messages in a VANET with other desirable security features have been heavily studied. However, there are still several issues to be addressed before such authentication mechanisms can be readily and widely used in real-life deployments. In this paper, we examine several proposed authentication solutions and categorize them based on certain criteria. We provide a comparison of the advantages and disadvantages of the proposed schemes identifying their suitability under various conditions. Finally, to foster further research in the area, we address some of the challenges that need to be tackled in the future in order to realize the deployment of VANETs.
