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.
Claims20
A method for authentication of a component class of a component for use in a vehicle, the method performed by the vehicle and comprising the steps of:
- obtaining from a certification authority a certification that an authentic component of a component class, the authentic component having a first cryptographic key being unique to the component class of the authentic component, is associated with a second cryptographic key;
- utilizing the second cryptographic key in cryptographic communication with the prospective component;
- and
- determining whether the prospective component is the authehtic component of the component class based on whether the second cryptographic key is successfully utilized in the cryptographic communication.
A system for authentication of a component class of a prospective component for use in a vehicle, the system comprising:
- a vehicle system obtaining from a certification authority a certification that an authentic component of a component class, the authentic component having a first cryptographic key being unique to the component class of the prospective component, is associated with a second cryptographic key;
- a cryptographic computing element utilizing the second cryptographic key in cryptographic communication with a prospective component;
- and
- the vehicle system determining whether the prospective component is an authentic component of the component class based on whether the cryptographic key is successfully utilized in the cryptographic communication.
