Abstract:
1. A computer-implemented method comprising: identifying a suspect node of a network that includes multiple nodes in wireless communication; in response to identifying the suspect node, initiating formation of a sub-network of the network by: wherein the suspect node is not a member of the sub-network, wherein, after formation of the sub-network, first communications between the suspect node and a device of the network are routed to or through at least one of the members of the sub-network, and wherein the sub-network is configured to enable second communications between members of the sub-network, wherein the second communications are communicated in a manner that is secured against access by the suspect node; and implementing a traffic masking process that obscures a pattern of communications within the network, wherein the traffic masking process includes communicating dummy packets via the network to obscure the pattern of the communications within the network, and wherein existence of the sub-network is masked from the suspect node by replacing one or more of the dummy packets with one or more packets of the second communications.
