Patent Images
1. A method for a authorization of a service technician for performing a service operation on a vehicle, the method performed by the vehicle and comprising the steps of:
- accessing a secure device having limited accessibility but being accessible by the service technician and storing a first cryptographic key associated with the service technician;
obtaining from a certification authority a certification that an authentic technician is associated with a second cryptographic key corresponding to the first cryptographic key;
utilizing the cryptographic key in cryptographic communication with the secure device; and
determining whether the service technician is the authentic technician based on whether the cryptographic key is successfully utilized in the cryptographic communication;
accessing a technician database to determine whether the service technician is indicated as authorized to perform the service operation; and
allowing the service technician to perform the service operation if the service technician is indicated as authorized to perform the service operation.
