A method and system for encrypting communications between two aircraft on the ground at an airport. Each aircraft is coupled to a ground network via a broadband over power line communications (BPL) network, which may be provided via the respective ground power connectors for each aircraft. A mutually authenticated communications channel is established between each aircraft via the ground network. A shared pairwise key is established at each aircraft. The shared pairwise key may be separately established based upon channel state characteristics such as channel attenuation, bandwidth or delay. In the alternative, the shared pairwise key may be shared from one aircraft to the other or may be generated from public keys based upon a predetermined protocol such as Diffie Hellman. Data encrypted using the shared pairwise key may then be transmitted from one aircraft to the other aircraft. The encrypted data may be transmitted via the PBL network or a separate wireless network. |
