Abstract
Official abstract text for this publication.
A method for securing communications in a vehicle-to-vehicle (V2V) system including an on-board computer of a broadcasting vehicle predicting a value for a vehicle parameter, generating a heavyweight signature corresponding to the predicted value, and obtaining an actual value for the vehicle parameter. The method also includes the computer comparing the predicted value to the actual value to determine if the predicted value bears a first relationship to the actual value. If the computer determines that the predicted value bears the relationship to the actual value, the on-board computer generates a lightweight authenticating signature to correspond to the predicted value and broadcasts a data message having the predicted value with the corresponding heavyweight authenticating signature and the corresponding lightweight authenticating signature.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-readable storage device comprising computer-executable instructions that, when executed by a processor, cause the processor to perform operations, for securing communications between a subject vehicle in which the device is used and at least one receiving vehicle, comprising: predicting a future value for a subject-vehicle parameter corresponding to a pre-identified future time, yielding a predicted future-vehicle-parameter value; generating a h…
