17. A method for performing an asymmetric key exchange with a vehicle, the method comprising:
-
receiving a first digital certificate, the first digital certificate comprising a first public key that corresponds to a first private key that is stored on a certificate authority; and receiving a second public key, a digital signature of the second public key, and a second digital certificate, wherein; the second public key corresponds to a second private key stored on the vehicle; the digital signature of the second public key is generated by a remote device using a third private key; and the second digital certificate was generated by the certificate authority and includes a third public key and a digital signature of the third public key, wherein the third public key corresponds to the third private key and the digital signature of the third public key is generated by the certificate authority using the first private key. - View Dependent Claims (18, 19, 20)
