Abstract

A process and mechanism, such as a system and/or computer-implemented method, for establishing verified and trusted communications between an upstream and a downstream node in a network or across many nodes in a multi-hop fashion, without needing direct communications from the downstream node to a central authority. Only a single node needs direct communications with the central authority, which may be the central authority itself acting in this capacity. Any other node in the network can connect to a node that is already verified, establish mutual trust, and itself become “upstream” to a new node or set of nodes. This process and mechanism can apply to any two nodes that are configured to communicate given the same set of conditions without any explicit or implicit multi-hop capability, however, the present process and mechanism is most applicable in multi-hop systems.
