Abstract

A method for verifying authenticity of a vehicle, including programming a device to sequentially change a device element to an altered device element according to a change device element algorithm, and attaching the device to the vehicle. The method also includes generating the altered device element, and verifying that the altered device element matches an expected device element generated by the algorithm.
