Secure Vehicular Communication for Safety Applications - A Measurement Study

In this paper, we explore the feasibility of vehicle-to-vehicle (V2V) secure communication using public key cryptography. We implement a prototype and test it extensively in real driving conditions. Measurement data indicate that the system is feasible in terms of delay and loss, and that we can usually expect better performance than typical simulation works predict. However, we find that traffic congestion and the performance of public key cryptography component can pose significant challenges.
