Secure routing based on degree of trust
First Claim
1. A method to improve routing security, the method comprising:
- assigning, by at least one processor, at least one level of trust to at least one network node; and
utilizing, by the at least one processor, the at least one level of trust to determine a degree of security of the at least one network node,wherein the at least one level of trust of the at least one network node is related to an amount of certainty of a physical location of the at least one network node that is attained from verification of the physical location by using satellite geolocation techniques, which use liveness information from at least one secure spot beam based authentication signal to derive at least one secret key, in order to obtain the physical location of the at least one network node.

Abstract
A system, method, and apparatus for secure routing based on a degree of trust are disclosed herein. The disclosed method involves assigning a level of trust to at least one network node, and utilizing the level of trust to determine a degree of security of the network node(s). The level of trust of the network node(s) is related to an amount of certainty of the physical location of the network node(s). The amount of certainty is attained from the network node(s) being located in a known secure location, and/or from verification of the physical location of the network node(s) by using satellite geolocation techniques or by using network ping ranging measurements. The method further involves utilizing the level of trust of the network node(s) to determine a degree of trust of at least one path for routing the data, where the path(s) includes at least one of the network nodes.

23. A system to improve routing security, the system comprising:
-
at least one network node; and at least one processor configured to assign at least one level of trust to the at least one network node, and configured to utilize the at least one level of trust to determine a degree of security of the at least one network node, wherein the at least one level of trust of the at least one network node is related to an amount of certainty of a physical location of the at least one network node that is attained from verification of the physical location by using satellite geolocation techniques, which use liveness information from at least one secure spot beam based authentication signal to derive at least one secret key, in order to obtain the physical location of the at least one network node.
