Patent ID: 11889392
Assignee: THE BOEING COMPANY
Field: Digital communication (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 9:
10. A network module for obfuscating mapping of an avionic network, wherein the network module is operatively coupled to the avionic network and configured to:
be operatively interposed between an avionics bus of the avionic network and an external-access node with all communications between the external-access node and the avionics bus passing through the network module;
generate a first one-to-one network map identifying substitute local network IP addresses for a set of components on at least a portion of the avionic network;
make the first network map on the network module accessible to the external-access node;
generate a second one-to-one network map identifying substitute local network IP addresses for the set of components, the second network map being different from the first network map; and
obfuscate network locations of the set of components by changing the network map accessible to the external-access node from the first network map to the second network map;
wherein the obfuscation maintains authorization of an external device to access the network through the external-access node; and
wherein any scanned network map of the avionics network from an external-access node is rendered ineffective once the accessible network map changes.
