Abstract
In at least one embodiment, a method and a system include a node potentially having information responsive to an information request distributed into, for example, a federated coalition network where the node receives at least one information request packet, conducts a search of information at the node to determine if requested information is present, when the requested information is present, then the node sends an acknowledgement to a requesting node, linear network codes the requested information into m packets where m is greater than or equal to k, which is the number of packets needed to be received by the requesting node to reconstruct the requested information, selects multiple paths between the node and the requesting node such that no third party will see more than k−1 different packets, and transmits the m packets distributed over the selected paths. In a further embodiment, the method and system include operation of the network to have the capability to provide responsive information in a protected way.
