Method and system for vehicle authentication of a remote access device
First Claim
1. A method for a vehicle securely communicating with a remote access device, the method performed by the vehicle and comprising the steps of:
- obtaining from a certification authority a certification that an authentic device is associated with a cryptographic key;
utilizing the cryptographic key in cryptographic communication with the remote access device;
determining whether the remote access device is the authentic device based on whether the cryptographic key is successfully utilized in the cryptographic communication; and
communicating further with the remote access device upon determining that the remote access device is the authentic device.

Abstract
A vehicle obtains from a certification authority a certification that an authentic device is associated with a cryptographic key. The certification certifies that the cryptographic key is bound to information identifying the authentic device. The vehicle utilizes the cryptographic key obtained from the certification authority in cryptographic communication with the remote access device, and determines whether the remote access device is the authentic device based on whether the cryptographic key is successfully utilized in the cryptographic communication. Upon determining the remote access device is the authentic device, the vehicle may communicate further with the remote access device.
