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.
