Abstract: A device-implemented network with domains each having nodes, the nodes of each of the domains sharing network information with one another according to an intra-domain communication policy. An inter-domain protocol is configured to control communication between at least one of the nodes of one of the domains and at least one of the nodes of a different one of the domains. A broker is configured to be communicatively coupled to the nodes and configured to control communication according to the inter-domain protocol and to which all of the nodes of each of the plurality of domains are configured to send the network information.

Abstract: Methods, networks and nodes for dynamically establishing encrypted communications between a first node having a first identification and a first private key and a second node having a second identification and a second private key. A first signal comprising information indicative of the first identification of the first node is transmitted, then, upon receipt of the first signal by the second node, a second signal comprising information indicative of the second identification of the second node and a first portion of a symmetric key is transmitted, then, upon receipt of the second signal by the first node, a third signal comprising a second portion of the symmetric key is transmitted.
