    • 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.
    • 在至少一个实施例中,方法和系统包括潜在地具有响应于分发到例如节点接收至少一个信息请求分组的联盟联盟网络的信息请求的信息的节点在 节点,以确定所请求的信息是否存在,当所请求的信息存在时,节点向请求节点发送确认,线性网络将请求的信息编码为m个分组,其中m大于或等于k,其是数字 需要由请求节点接收以重构所请求的信息的分组,选择节点和请求节点之间的多个路径,使得没有第三方将看到超过k -1个不同的分组,并且发送分布在所选择的 路径。
