AIRCRAFT NETWORK CYBERSECURITY APPARATUS AND METHODS

A method of obfuscating mapping of an avionic network is disclosed, including operatively coupling a network module between an external-access node and an avionics bus, with all communications between the external-access node and the avionics bus passing through the network module. The method furthe...

More Information
Summary:A method of obfuscating mapping of an avionic network is disclosed, including operatively coupling a network module between an external-access node and an avionics bus, with all communications between the external-access node and the avionics bus passing through the network module. The method further includes generating a first network map identifying network addresses for a first set of components on at least a first portion of the avionics bus, loading the first network map on the network module, and making the first network map accessible to the external access node. The method further includes generating at least a second network map different from the first network map and loading the second network map on the network module. The method further includes changing the network map accessible to the external-access node from the first network map to the second network map.
