1. A method of selectively verifying and processing messages within a vehicle-to-vehicle communication system, the method comprising the steps of:

  • (a) a host vehicle receiving a message in the vehicle-to-vehicle communication system from a remote vehicle;

    (b) evaluating a time-to-collision status between the host vehicle and the remote vehicle sending the message, the time-to-collision status being a function of a relative distance and a relative velocity between the host vehicle and the remote vehicle which are determined from data provided within a first portion of the message received from the respective remote vehicle;

    (c) assigning an attentive factor to the remote vehicle based on the time-to-collision status, the attentive factor for a remote vehicle identifying a proportion of messages broadcast from the remote vehicle to be targeted for security processing;

    (d) performing security processing of the message using a second portion of the message unless the attentive factor indicates the message should be ignored; and

    (e) returning to step (a) for each subsequent message.
