Claims
- 1. 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.
- 2. The method of claim 1 wherein the certification comprises a digital certificate.
- 3. The method of claim 1 wherein the certification comprises a digital signature of the certification authority.
- 4. The method of claim 1 wherein the certification authority is authenticated by a second certification authority.
- 5. The method of claim 1 wherein the certification authority is a component supplier of the authentic component.
- 6. The method of claim 1 wherein the first cryptographic key is a private cryptographic key of the prospective component and accessible only by the prospective component.
- 7. The method of claim 6 wherein the second cryptographic key is a public cryptographic key of the authentic component.
- 8. The method of claim 1, further comprising the step of obtaining authorization from the vehicle to become operative upon successfully utilizing the first cryptographic key in cryptographic communication with the vehicle.
- 9. The method of claim 8 wherein authorization to become operative is not obtained unless the vehicle determines the certification authority to be authorized to authenticate the authentic component.
- 10. The method of claim 1 wherein the certification associates the second cryptographic key with an attribute of the authentic component.
- 11. 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.
- 12. The component of claim 11 wherein the second cryptographic key is certified to be associated with the authentic component by a digital certificate.
- 13. The component of claim 11 wherein the digital certificate comprises a digital signature of the certification authority.
- 14. The component of claim 11 wherein the certification authority is authenticated by a second certification authority.
- 15. The component of claim 11 wherein the certification authority is a component supplier of the authentic component.
- 16. The component of claim 11 wherein the first cryptographic key is a private cryptographic key of the prospective component.
- 17. The component of claim 16 wherein the private cryptographic key is accessible only by the prospective component.
- 18. The prospective component of claim 16 wherein the second cryptographic key is a public cryptographic key of the authentic component.
- 19. The component of claim 11 wherein the cryptographic computing element upon successfully utilizing the first cryptographic key in cryptographic communication with the vehicle allows the component to obtain authorization to become operative in the vehicle.
- 20. The method of claim 11 wherein the certification associates the second cryptographic key with an attribute of the authentic component.
