Method and system for vehicle component authentication of another vehicle component
First Claim
1. A method for authentication of a prospective component for use in a vehicle having a configured component, the method performed by the configured component and comprising the steps of:
- 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 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.

Abstract
A configured component of a vehicle obtains 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, and may be implemented, for example, with a digital certificate obtained from a certificate authority. The configured component 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. Upon determining the prospective component is the authentic component, the configured component may allow the prospective vehicle to operate the component.
