Vehicular Communication and VANETs

The future and security of communicating vehicles

Vehicle communication is a major research topic, covered by many national and international research projects. Applications promise to make our driving safer, more efficient, and more fun. The talk presents applications, technology, and also addresses security and privacy issues.

The talk will first introduce the concept of vehicle communication. Vehicles can communicate with each other to form so called Vehicular Ad-hoc Networks (VANETs) or with road-side units that allow access to backend systems that provide warnings, traffic information, etc.

Next, there will be a presentation of potential applications to motivate the need for such communication. This includes warning applications, e.g. cars can send warning messages to other cars including their exact position warning them of the danger ahead. As cars receiving such messages will forward them also to other cars, they form a multi-hop ad-hoc network. Other applications can warn cars about dangerous road conditions, increase traffic efficiency at intersections or on highways or may simply be used to send e.g. text messages between cars (did you ever wanted to tell the driver in front of you your oppinion regarding his driving style?;-)

The talk will also cover technical details like position-based routing used in such networks or message dissemination protocols.

It is evident that such systems will also introduce new dangers to security and privacy. Sending e.g. faked warning messages may affect traffic and recording the position information of cars severly affects the privacy of drivers. The speaker is member of the pan-european research project SEVECOM that especially addresses the security and privacy needs in car communication. He will present some results from the that project, describing security requirements, potential attackes, and first ideas for security and privacy mechanisms.
