Method and system for authorizing reconfiguration of a vehicle
First Claim
1. A method for authorizing reconfiguration of a vehicle, the method performed by the vehicle and comprising the steps of:
- 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 a prospective component for a reconfiguration function;
determining whether the prospective component is the authentic component based on whether the cryptographic key is successfully utilized in the cryptographic communication;
accessing, upon determining the prospective component is the authentic component, a configuration database to determine whether the reconfiguration function is authorized; and
allowing the reconfiguration function to be performed upon determining that the reconfiguration function is authorized.

Abstract
A vehicle accesses a configuration database to determine whether a reconfiguration function is authorized. The reconfiguration function may involve, for example, installing the component in the vehicle, removing the component from the vehicle, replacing the component with another component in the vehicle, replacing another component in the vehicle with the component, modifying the component, upgrading the component and rendering the component operable. Upon determining that the reconfiguration function is authorized, the vehicle allows the reconfiguration function to be performed. The reconfiguration function may be authorized based on a type of the vehicle, a type of the component or a combination of configuration elements in a current configuration of the vehicle.
