Method and system for vehicle authentication of a remote access 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.
