Restore of headless electronic device

An authorization device for restoring a setting on a network connected device, said authorization device connected to the network connected device as an adjacent node on the network, within a network segment, and said authorization device comprising:

• a controller;
• a non-volatile storage for software and certificates;
• a port, operatively connected to the controller and the non-volatile storage, for Ethernet communication with the network connected device;
• the port configured to transmit, to the network connected device, within the network segment, via low level link layer packets, an initiation signal representing a request to restore the setting on the network connected device, wherein the initiation signal is triggered by the actuation of a restore button arranged on the authorization device;
• the port configured to receive, from the network connected device via the low level link layer packets, a fully or partially encrypted request for authorization to restore the setting;
• and
• the port configured to transmit, to the network connected device via the low level link layer packets, a fully or partially encrypted restore authorization message, for restoring settings on the network connected device, to the network connected device in response to the received request for authorization.

A system for restoring a setting of a network connected device, said system comprising:

• the network connected device, connected to an authorization device as an adjacent node on the network, within a network segment, configured to receive, from the authorization device over a low level layer protocol, an initiation signal representing a request to restore the setting on the network connected device, wherein the initiation signal is triggered by the actuation of a restore button arranged on the authorization device;
• the network connected device configured to transmit, to the authorization device over the low level link layer protocol, a fully or partially encrypted request for authorization to restore the setting is transmitted in response to the received initiation signal;
• at the network connected device:
• receiving a fully or partially encrypted restore authorization message from the authorization device over the low level link layer protocol in response to the transmitted request for authorization;
• decrypting the received restore authorization message;
• verifying the received restore authorization message;
• and
• restoring the settings on the network connected device if the received restore authorization message was verified.
