DOMAIN ESTABLISHMENT, REGISTRATION AND RESIGNATION VIA A PUSH BUTTON MECHANISM

A network node includes a pushbutton to provide a button-press event and a pairer to receive the button-press event while not being in a secure domain. In response to the button-press, the pairer alternates between acting as an endpoint node and acting as a temporary domain master, until pairing is completed. In an alternative embodiment, the node includes a multi-pairer to receive the button press event and, in response, to open a pairing window, to become a domain master of a secure network and to join more than one other network node receiving a button press event to the secure network until the pairing window closes.
