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