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

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