Abstract

A method of operating a secure wireless network between a master controller and a secure device is provided. The method comprising: detecting at least one of a NONCE-GET and a NONCE-REPORT using a sniffer configured to detect wireless signals from a selected wireless protocol; determining that the NONCE-GET was not transmitted by a master controller or that the NONCE-REPORT was not in response to a NONCE-GET transmitted by the master controller, the master controller being in electronic communication with the sniffer; and transmitting a new NONCE-GET to the secure device from the master controller.

Claims (41)

1. A method of operating a secure wireless network between a master controller and a secure device, the method comprising:

detecting at least one of a NONCE-GET and a NONCE-REPORT using a sniffer configured to detect wireless signals from a selected wireless protocol;

determining that the NONCE-GET was not transmitted by a master controller or that the NONCE-REPORT was not in response to a NONCE-GET transmitted by the master controller, the master controller being in electronic communication with the sniffer;

determining that an intruder is attempting to perform a hack attempt on the secure device to gain access to the secure device based on determining that the NONCE-GET was not transmitted by the master controller or that the NONCE-REPORT was not in response to the NONCE-GET transmitted by the master controller;

initiating a counterattack in response to the hack attempt to prevent the intruder from gaining access to the secure device by transmitting a new NONCE-GET to the secure device from the master controller to obtain a new key so that the master controller and the secure device can operate over a new secure connection; and

restoring the state of the secured device after the master controller transmits the new NONCE-GET to the secure device;

wherein the selected wireless protocol is Z-Wave protocol.

2. The method of claim 1 , wherein:

the sniffer is separate and apart from the master controller.

3. The method of claim 1 , wherein:

the sniffer is contained within the master controller.

4. The method of claim 1 , further comprising:

activating an alarm on the master controller when it is determined that the NONCE-GET was not transmitted by a master controller or that the NONCE-REPORT was not in response to a NONCE-GET transmitted by the master controller.

5. A wireless communication security system comprising:

a sniffer configured to detect wireless signals from a selected wireless protocol;

a master controller in electronic communication with the sniffer and configured to wirelessly control a secure device, the master controller comprising;

a processor;

a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:

detecting at least one of a NONCE-GET and a NONCE-REPORT using the sniffer;

determining that the NONCE-GET was not transmitted by a master controller or that the NONCE-REPORT was not in response to a NONCE-GET transmitted by the master controller, the master controller being in electronic communication with the sniffer; determining that an intruder is attempting to perform a hack attempt on the secure device to gain access to the secure device based on determining that the NONCE-GET was not transmitted by the master controller or that the NONCE-REPORT was not in response to the NONCE-GET transmitted by the master controller;

initiating a counterattack in response to the hack attempt to prevent the intruder from gaining access to the secure device by transmitting a new NONCE-GET to the secure device from the master controller to obtain a new key so that the master controller and the secure device can operate over a new secure connection; and

restoring the state of the secured device after the master controller transmits the new NONCE-GET to the secure device;

wherein the selected wireless protocol is Z-Wave protocol.

6. The wireless communication security system of claim 5 , wherein:

the sniffer is separate and apart from the master controller.

7. The wireless communication security system of claim 5 , wherein:

the sniffer is contained within the master controller.

8. The wireless communication security system of claim 5 , wherein the operations further comprise:

activating an alarm on the master controller when it is determined that the NONCE-GET was not transmitted by a master controller or that the NONCE-REPORT was not in response to a NONCE-GET transmitted by the master controller.

9. A computer program product tangibly embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

detecting at least one of a NONCE-GET and a NONCE-REPORT using a sniffer configured to detect wireless signals from a selected wireless protocol;

determining that the NONCE-GET was not transmitted by a master controller or that that the NONCE-REPORT was not in response to a NONCE-GET transmitted by the master controller, the master controller being in electronic communication with the sniffer; determining that an intruder is attempting to perform a hack attempt on the secure device to gain access to the secure device based on determining that the NONCE-GET was not transmitted by the master controller or that the NONCE-REPORT was not in response to the NONCE-GET transmitted by the master controller;

initiating a counterattack in response to the hack attempt to prevent the intruder from gaining access to the secure device by transmitting a new NONCE-GET to a secure device from the master controller to obtain a new key so that the master controller and the secure device can operate over a new secure connection;

restoring the state of the secured device after the master controller transmits the new NONCE-GET to the secure device;

wherein the selected wireless protocol is Z-Wave protocol.

10. The computer program of claim 9 , wherein:

the sniffer is separate and apart from the master controller.

11. The computer program of claim 9 , wherein:

the sniffer is contained within the master controller.

12. The computer program of claim 9 , wherein the operations further comprise:

activating an alarm on the master controller when it is determined that the NONCE-GET was not transmitted by a master controller or that the NONCE-REPORT was not in response to a NONCE-GET transmitted by the master controller.
