Abstract: A computer-implemented method includes: receiving, by an authentication device, from a client device and via a network device, a plurality of passcode packets as part of a request to be authenticated by the authentication device; recording, by the authentication device, a sequence of port identifiers corresponding to respective ports of the network device via which the plurality of passcode packets are received; and authenticating, by the authentication device, the client device based on the sequence of port identifiers.

Abstract: A vehicle network system is configured to detect unauthorized intrusions by a passenger-owned device, and to identify the passenger-owned device based at least in part on stored information representative of network communications. The vehicle network system can be further configured to determine a position of the intruding passenger-owned device within a passenger area of the vehicle and to obtain a name and/or camera image of a passenger associated with the device. The position of the intruding device can be identified based at least in part on communications between the intruding device and one or more network-access devices distributed throughout the passenger area.

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.
