Mapping of an avionic network is obfuscated by interposing a network module between an external-access node and a bus of an avionics network. First and second network maps are generated and loaded on the network module. The network map accessible to the external-access node is changed from the first network map to the second network map, to disrupt any reconnaissance of the avionics network.

Aircraft network cybersecurity apparatus and methods

Systems for and methods of securely communicating between a ground station and an aircraft are presented. The communications are among a plurality of nodes, including a ground based node and a plurality of aircraft based nodes. Each node stores at least a respective portion of a blockchain representing interactions among at least some of the nodes. Control nodes may initiate a privileged network action by: broadcasting to the plurality of control nodes a blockchain record representing the privileged network action, receiving from control nodes a plurality of votes representing validation results of the privileged network action, determining that a consensus from the control node votes indicates that the privileged action is permissible, and publishing to respective blockchain portions of each of the plurality of nodes a derivation of the blockchain record representing the privileged action, where the system implements the privileged action based on the determining.
