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