Abstract

Official abstract text for this publication.

A system, method, and apparatus for the authentication of the physical location of a target node are disclosed herein. In one or more embodiments, the authentication of the target node's physical location is achieved by using ping ranging measurements obtained from the amount of time that elapses during ping messages being sent between the target node and at least one trusted node with a known physical location. The physical location of the trusted node(s) is obtained by using satellite geolocation techniques. The accuracy of the ranging measurements may be improved upon by using pre-coordination and/or priority determination of the ping messages being sent between the target node and the trusted node(s). In at least one embodiment, the ping messages are sent by dedicated ping response hardware that is associated with the target node and/or the trusted node(s). In some embodiments, the ping messages include a pseudo random code bit sequence.

First claim

Opening claim text (preview).

We claim: 1. A method for authenticating a physical location of a target node, the method comprising: sending, by the target node, a geothentication request to at least one trusted node with a known physical location; receiving, by the at least one trusted node, the geothentication request; sending, by the at least one trusted node, an inquiry message to the target node; receiving, by the target node, the inquiry message; sending, by the target node, a response message to…
