Claims
- 1. A method for authentication of a component for use in a vehicle subassembly of a vehicle, the method performed by the vehicle subassembly and comprising the steps of:
obtaining a prospective component; obtaining from a certification authority a certification that an authentic component is associated with a cryptographic key; utilizing the cryptographic key in cryptographic communication with the prospective component; and determining whether the prospective component is the authentic component based on whether the cryptographic key is successfully utilized in the cryptographic communication with the prospective component.
- 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, further comprising the step of determining that the certification authority is authorized to certify the authentic component.
- 7. The method of claim 1 wherein the step of obtaining the certification comprises obtaining a certification that a component having an identified attribute is associated with the cryptographic key.
- 8. The method of claim 1 wherein the step of obtaining the certification comprises obtaining a certification that a component having an identified component supplier is associated with the cryptographic key.
- 9. The method of claim 1 wherein the authentic component has a first cryptographic key and the cryptographic key with which the certification associates the authentic component is a second cryptographic key corresponding to the first cryptographic key.
- 10. The method of claim 9 wherein the first cryptographic key is accessible only by the authentic component.
- 11. The method of claim 9 wherein the first cryptographic key is a private cryptographic key of the authentic component and the second cryptographic key is a public cryptographic key of the authentic component.
- 12. The method of claim 1, further comprising the step of allowing the prospective component to become operative within the vehicle subassembly upon determining the prospective component is the authentic component.
- 13. The method of claim 1, wherein the vehicle subassembly is authenticated by a vehicle system of the vehicle.
- 14. The method of claim 1, wherein the vehicle subassembly is authenticated by a configured component of the vehicle.
- 15. The method of claim 1, wherein the vehicle subassembly is authenticated by a vehicle system of the vehicle.
- 16. A system for vehicle authentication of a component for use in the vehicle subassembly of a vehicle, the system comprising:
a subassembly system obtaining from a certification authority a certification that an authentic component is associated with a cryptographic key, the vehicle system comprising
a cryptographic unit utilizing the cryptographic key in cryptographic communication with a prospective component; and a computing unit determining whether the prospective component is the authentic component based on whether the cryptographic key is successfully utilized in the cryptographic communication.
- 17. The system of claim 16 wherein the certification comprises a digital certificate.
- 18. The system of claim 16 wherein the certification comprises a digital signature of the certification authority.
- 19. The system of claim 16 wherein the certification authority is authenticated by a second certification authority.
- 20. The system of claim 16 wherein the certification authority is a component supplier of the authentic component.
- 21. The system of claim 16, wherein the vehicle system determines that the certification authority is authorized to certify the authentic component.
- 22. The system of claim 16 wherein the certification comprises a certification that a component having an identified attribute is associated with the cryptographic key.
- 23. The system of claim 16 wherein the certification comprises a certification that a component having an identified component supplier is associated with the cryptographic key.
- 24. The system of claim 16 wherein the authentic component has a first cryptographic key and the cryptographic key with which the certification associates the authentic component is a second cryptographic key corresponding to the first cryptographic key.
- 25. The system of claim 24 wherein the private cryptographic key is accessible only by the authentic component.
- 26. The system of claim 24 wherein the first cryptographic key is a private cryptographic key of the authentic component and the second cryptographic key is a public cryptographic key of the authentic component.
- 27. The system of claim 16 wherein the computing unit allows the prospective component to become operative within the vehicle upon determining the prospective component is the authentic component.
- 28. The system of claim 16, further comprising a vehicle system authenticating the vehicle subassembly.
- 29. The system of claim 16, further comprising a configured component authenticating the vehicle subassembly.
- 30. The system of claim 16, further comprising a configured vehicle subassembly authenticating the vehicle subassembly.
