Method and system for technician authentication of a vehicle
First Claim
1. A method for authentication of a prospective vehicle by a service technician for performing a service operation on the prospective vehicle, the method performed by the service technician and a secure device, and comprising the steps of:
- accessing the prospective vehicle;
obtaining from a certification authority a digital signature, wherein the digital signature certifies the prospective vehicle as an authentic vehicle and certifies an identified attribute of the authentic vehicle, and wherein the digital signature is associated with a certificate that comprises an attribute identifying the authentic vehicle and a cryptographic key, wherein the cryptographic key is bound to the authentic vehicle;
utilizing the cryptographic key in cryptographic communication with the prospective vehicle via a secure device having limited accessibility but being accessible by the service technician; and
determining whether the prospective vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication.

Abstract
The service technician accesses the prospective vehicle and obtains from a certification authority a certification that an authentic vehicle is associated with a cryptographic key. The service technician utilizes the cryptographic key in cryptographic communication with the prospective vehicle via a secure device having limited accessibility but being accessible by the service technician. The service technician determines whether the prospective vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication with the prospective vehicle.

10. A method for authentication of a prospective vehicle by a service technician for performing a service operation on the prospective vehicle, the method performed by the service technician and a secure device, and comprising the steps of:
-
accessing the prospective vehicle; obtaining for the secure device a digital signature, wherein the digital signature certifies the prospective vehicle as an authentic vehicle and certifies an identified attribute of the authentic vehicle, and wherein the digital signature is associated with a certificate that comprises an attribute identifying the authentic vehicle and a secret cryptographic key stared therein; challenging the prospective vehicle utilizing the secret cryptographic key in cryptographic communication via the secure device; encrypting the challenge by the prospective vehicle using a private key stored therein; decrypting the challenge using the secret key of the secure device; and determining whether the prospective vehicle is the authentic vehicle based on whether the decrypted challenge in the cryptographic communication is the same as the original challenge.
