Blockchain fortified aircraft communications addressing and reporting system (ACARS) communication

Abstract:

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.
