Abstract
A method and system for providing a secure communication network using an electrical distribution grid is disclosed. A device connected to the electrical distribution grid initiates a request for a secured key token by signaling an intelligent communicating device residing at or near an edge of the grid. The intelligent communicating device forwards the request to a receiver at a distribution substation on the electrical grid. This receiver enhances the properties of the request such that a grid location for the request can be inferred. The enhanced request is forwarded to a server at the distribution substation, which compares the request grid location to a Grid Map and Policies of known secure grid locations. Any inconsistencies between the grid location inferred from the enhanced request and the Grid Map and Policies locations are considered evidence of tampering, and the server rejects the request.

65. A system for the establishment and maintenance of secure communications paths, comprising:
-
an electrical distribution grid comprising at least one distribution substation; an intelligent communicating device located at or near the edge of an electrical distribution grid, wherein the intelligent communicating device uses at least the electrical distribution grid as a transmission medium; a server located at the distribution substation; a receiver connected to the server at the substation; and a device associated with the intelligent communicating device, wherein a location of the device on the electrical distribution grid is determined inferred by a receiver at the distribution substation.
