Method and system for component authentication of a vehicle
First Claim
1. A method for authentication of a prospective vehicle by a component for use in the prospective vehicle, the method performed by the component and comprising the steps of:
- accessing, by the component, the prospective vehicle, wherein the component has at least a component computing unit, a component cryptographic unit, a component memory, the component memory storing data related to the component;
obtaining from a certification authority a certification that an authentic vehicle is associated with a cryptographic key;
utilizing, by the component cryptographic unit, the cryptographic key in cryptographic communication with a cryptographic unit of the prospective vehicle; and
determining, by the component, whether the prospective vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication.

Abstract
A component for use in a prospective vehicle obtains from a certification authority a certification that an authentic vehicle is associated with a cryptographic key. The certification certifies that the cryptographic key is bound to information identifying the authentic vehicle. The component utilizes the cryptographic key obtained from the certification authority in cryptographic communication with the prospective vehicle, and determines whether the prospective vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication. Upon determining the prospective vehicle is the authentic vehicle, the component may allow the prospective vehicle to operate the component.
