Keyless Message Authentication by Verifying Position and Velocity for Inter-Vehicle Communication 2006-01-1582

Inter-vehicle communication is being considered as a means for increasing safety and efficiency in future intelligent highways. However, the security in these future mobile ad hoc networks of vehicles should not be an after thought. The main challenges in developing such security schemes are the highly dynamic environment and the cost restrictions. In this paper, we propose a keyless scheme for message authentication in inter-vehicle communication by verifying the sender’s position and velocity. The approach relies on signal propagation time to authenticate messages being communicated. No infrastructure or dedicated hardware beyond standard GPS is required.
