A system and method for a vehicle-to-vehicle communications system that provide active safety applications employing lightweight geographic authentication using one-time signatures. The system and method require each vehicle to construct a discretized representation of its trajectory, which captures its kinematical history to a tunable degree of accuracy and to a tunable extent in the past. This trajectory information is then signed using a one-time signature. Thus, with every periodic message, the sending vehicle transmits the usual application payload, a signed version of the trajectory as described, and the digital signature over all of the fields.
