Abstract
A prospective component for use in a vehicle stores a first cryptographic key and utilizes the first cryptographic key in cryptographic communication with the vehicle. The vehicle obtains from a certification authority a certification associating a second cryptographic key with an authentic component. The vehicle utilizes the second cryptographic key in cryptographic communication and determines whether the prospective component is the authentic component based on whether the cryptographic communication is successful.
