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 hyberbolic 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.

Claims

1. A method of authenticating a network device, the method comprising:

providing identification information of a first network device to a second network device and a third network device, wherein the identification information comprises location information of the first network device and a timestamp;

verifying the location information of the first network device by a hyberbolic verification scheme, wherein verification is performed by the second network device and the third network device; and

authenticating the first network device based on the verification.

2. The method as claimed in claim 1, wherein the first network device communicates with the second network device and the third network device via at least one of Wifi networks, Wimax networks, Near field communication networks (NFC), sound based communication networks, multimedia based communication networks and Bluetooth networks.

3. The method as claimed in claim 1, wherein authenticating the first network device comprises

generating a location based data encryption key for the first network device.

4. The method as claimed in claim 1 and further comprising:

sending the location information as public key to one or more network devices subsequent to authentication.

5. A method of authenticating a network device in a location based verification framework, the method comprising:

transmitting a first message from the network device via a network, wherein the first message comprises a timestamp indicating time of broadcast of the first message;

calculating distance of the network device from a first verifier device, wherein the distance of the network device from the first verifier device is proportional to time taken by the message to propagate from the network device to the first verifier device;

calculating distance of the network device from a second verifier device, wherein the distance of the network device from the second verifier device is proportional to time taken by the message to propagate from the network device to the second verifier device;

verifying the location of the network device to be within a set of locations represented by a hyperbola;

transmitting a second message from one of the first verifier device and the second verifier device;

receiving a third message at the first verifier device and the second verifier device, wherein the network device sends the third message in response to the second message; and

authenticating the network device to the network.

6. The method as claimed in claim 5, wherein the network device communicates with the first verifier device and the second verifier device via at least one of Wifi networks, Wimax networks, Near field communication networks (NFC), sound based communication networks, multimedia based communication networks and Bluetooth networks.

7. The method as claimed in claim 5, wherein the first verifier device and the second verifier device communicate via a secure communication channel.

8. The method as claimed in claim 5, wherein the verification of the location of the network device occurs in the first verifier device and the second verifier device.

9. The method as claimed in claim 5, wherein time taken for the first message to propagate from the network device to the first verifier device is the time difference between a first instance when the first verifier device receives the first message and time indicated by the first timestamp.

10. The method as claimed in claim 5, wherein time taken for the first message to propagate from the network device to the second verifier device is the time difference between a second instance when the first verifier device receives the first message and time indicated by the first timestamp.

11. The method as claimed in claim 5, wherein authenticating the network device comprises

generating a location based data encryption key for the network device.

12. The method as claimed in claim 5, wherein the location based verification framework is also used for Universal Plug and Play devices in a Home Network scenario.

13. A system of authenticating a network device, the system comprising:

a plurality of network devices;

a verifying module to verify location information of a network device; and

an authenticating module to authenticate the network device based on verification.

14. The system as claimed in claim 13 and further comprising:

a communication channel to enable communication between the plurality of network devices.

15. The system as claimed in claim 13 wherein the communication channel is at least one of Wifi networks, Wimax networks, Near field communication networks (NFC), sound based communication networks, multimedia based communication networks and Bluetooth networks.
