1. A method of authenticating a network device, the method comprising:
- receiving a first signal including a timestamp indicating time of broadcast of the first signal of a first network device from the first network device;
calculating a first distance between the first network device and a second network device using the timestamp;
receiving, from a third network device, a second distance between the first network device and the third network device calculated using the timestamp;
calculating a location of the first network device based on the calculated first distance and the received second distance;
verifying location of the first network device based on the calculated location of the first network device; and
authenticating the first network device based on the verification,wherein the verifying further comprises;
transmitting a second signal including a first nonce message to the first network device, andin response to the second signal, receiving a third signal including a second nonce message from the first network device.

Abstract
A method and system of authenticating a network device includes providing identification information of a first network device to a second network device and a third network device. The identification information includes location information of the first network device and a timestamp. The method includes verifying the location information of the first network device by a hyperbolic verification scheme. The verification is performed by the second network device and the third network device. The method includes authenticating the first network device based on the verification.

11. A system of authenticating a network device, the system comprising:
-
a plurality of network devices; and a verifying module to verify location information of a network device; and an authenticating module to authenticate the network device based on verification, wherein the network device transmits identification information of the network device to at least two other network devices among the plurality of network devices via a communication channel, wherein the identification information comprises location information of the network device and a timestamp, wherein the verifying module is configured to verify a location of the network device based on calculated locations of the network device by the at least two other network devices, wherein a first other network device calculates a first distance between the network device and the first other network device using timestamps, wherein a second other network device calculates a second distance between the network device and the second other network device using the timestamps, wherein the first other network device and the second other network device calculate the location of the network device from the first distance and the second distance, wherein one of the first other network device and the second other network device transmits a first signal including a first nonce message to the network device, and wherein, in response to the first signal, the network device transmits a second signal including a second nonce message to the first other network device and the second other network device. - View Dependent Claims (12, 13, 14)
