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