ABSTRACT:
A vehicle authenticates a first prospective component by obtaining from a certification authority a certification that an authentic component is associated with a cryptographic key unique to the first prospective component and determining whether the first prospective component is the authentic component based on whether the cryptographic key is successfully utilized in cryptographic communication with the first prospective component. The vehicle authenticates a component class of a second prospective component by obtaining from a certification authority a certification that an authentic component of the component class is associated with a second cryptographic key unique to the component class and determining whether the second prospective component is an authentic component of the component class based on whether the second cryptographic key is successfully utilized in the cryptographic communication with the second prospective component.
