Both modern high-speed motorways and vehicles that drive upon them are becoming increasingly intelligent. In particular, communication devices are being installed in more and more cars and roadside infrastructure components. In the not-too-distant future, traveling vehicles will be able to communicate while forming ephemeral, rapidly changing ad hoc networks. At the same time, they will have direct access to a fixed roadside network infrastructure with information flowing both ways. This network environment motivates the need for an infrastructure that will provide drivers with access to a variety of vital vehicular and roadside information. The resulting enhanced situational awareness has the potential to not only facilitate the decision making tasks of the drivers but also to improve highway safety (by bringing information about catastrophic events and road conditions to the driver's attention). The objective is to explore the security-related challenges in this envisaged setting. While this paper presents no solid technical results, it can believed that it provides a valuable analysis of an environment that is very likely to become real in the near future. In particular, it describes one instantiation of an information infrastructure for highway driver assistance: DAHNI (Driver Ad Hoc Networking Infrastructure). The paper starts with the brief overview of some key technology assumptions in the next section. Then a couple of promising applications (Section 3) will be considered and turn to the discussion of specific security issues.
