Abstract
A method for providing secure connection between vehicles. A unique pair of digitally signed public key and private key is provided to each vehicle, along with additional vehicle-related data. A certificate number is generated for each vehicle and the public key, the certificate number and the attributes of the vehicle is signed by a trusted certificate generating authority. Before communicating with a second vehicle, the first vehicle sends its unique certificate to a second vehicle; the second vehicle verifies the authenticity of received unique certificate number and visible attributes by a camera. If the attributes are verified successfully, the second vehicle sends its unique certificate number to the first vehicle, along with a secret key, which is valid for the current session only. Then the first vehicle verifies the authenticity of received certificate of the second vehicle and attributes by a camera that captures visible attributes of the second vehicle.
