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.
