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.
