Classification: CPC H  B | IPC B  H

Claim 0:
1. A method of obfuscating mapping of an avionic network, comprising:
operatively coupling a network module between an external-access node and an avionics bus of the avionic network with all communications between the external-access node and the avionics bus passing through the network module;
generating, by means of a randomization engine, a first network map identifying one-to-one network address translations for a set of components on at least a portion of the avionics bus;
loading the first network map on the network module;
making the first network map on the network module accessible to the external-access node;
generating, by means of a randomization engine, at least a second network map identifying one-to-one network address translations for the set of components, the second network map being different from the first network map,
loading the second network map on the network module;
disrupting any reconnaissance of the avionic network by changing the network map accessible to the external-access node from the first network map to the second network map;
wherein disrupting reconnaissance 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.
