Abstract: A method includes receiving, by a computing system, a first authenticated signal that (i) identifies a first position of a first aircraft relative to a host aircraft on which the computing system is located and (ii) includes a first identifier of the first aircraft, receiving, at a subsequent time, a second signal that is an ADS-B signal that identifies a second position, a velocity, and an aircraft type, where the second signal includes a second identifier, based on matching the first identifier and the second identifier such that the second signal corresponds to the first aircraft, using the first position and the aircraft type to confirm that it is possible that the first aircraft is located at the second position moving at the velocity at the subsequent time, and based on a confirmation that it is possible, providing an indication that the second signal is authentic.

Abstract: In general, certain embodiments of the present disclosure provide techniques or mechanisms for automatically filtering network messages in an aviation network for an aircraft based on a current system context. According to various embodiments, a method is provided comprising receiving a network message transmitted from a source avionic device to a destination avionic device via one or more network packets within the aviation network. A current system context, indicating an aggregate status of avionic devices within the aviation network, is determined based on monitoring the avionic devices. The network message is analyzed by identifying a plurality of attributes corresponding to header and data fields of the one or more network packets corresponding to the network message. The acceptability of the network message within the current system context is determined based on one or more filter rules that specify what attributes are allowed within a particular system context.

Abstract: In general, certain embodiments of the present disclosure provide methods and systems for automatic generation of filter rules based on functional network flows for e-Enabled aviation systems. According to various embodiments, a method is provided comprising capturing network packets corresponding to a functional network flow transmitted within a networked aviation system, and parsing the network packets in order to extract one or more network messages corresponding to the functional network flow. The network message is examined in order to identify and classify a plurality of attributes corresponding to the header and data fields of the network packets. A table corresponding to the network messages is automatically generated, which includes one or more filter rules. In some embodiments, the table may be used to determine which communications are authorized during a particular context of the networked aviation system. The method further comprises validating the one or more filter rules.

Abstract: A network system of an aircraft implements a target system to attract, detect, log, and mitigate a potential breach by the malicious entities. The target system simulates the systems of the aircraft in order to attract a potential breach. The target system simulates the data, file structure, communications, etc., of the systems of the aircraft. The target system includes little, or no security or access controls in order to attract a potential breach and allow the malicious entity to gain access. Once a breach occurs, the target system can be configured to log, report, and/or mitigate the potential breach.

Abstract: A method and apparatus for providing a self-compressing supersonic flow is provided by use of a contoured supersonic nozzle design. The shape of the supersonic nozzle array can be composed of curved blades which provide a focusing effect for a supersonic flow which will provide a gradient change in mach number along the supersonic flow path and efficient pressure recovery. Ideal design permits the self-compressing flow to have a secondary throat with down stream mach number of approximately one. As a result, a gas dynamic laser will have a well defined lasing region shortly after the increase in velocity of the working fluid to supersonic speeds. Controlled shaping of the supersonic flow is provided by means which will either use high speed jets or the Coanda effect. Further refining of the shape of the flow can permit the lasing region to take on the shape of a torus.
