Abstract
An identification code (referred to as “original identification code”) in a predetermined application is preset in each of one or more devices not compliant to a predetermined security protocol. A GW determines a new identification code of each of the one or more devices and notifies an HEMS controller of the new identification code. The GW receives a message including the new identification code of a particular device (referred to as “destination device”) and encrypted according to the security protocol. The GW decodes a received message according to the security protocol, converts the new identification code of the destination device included in a decoded message into the original identification code of the destination device, and transfers a converted message to the destination device.
