Abstract
A method for restoring a setting on a network connected device achieves increased security. The method includes receiving an initiation signal representing a request to restore the setting on the device; transmitting a request for authorization to restore the setting to an authorization device arranged as an adjacent node on the network by transmitting the request for authorization over a link layer protocol, wherein the request is transmitted in response to the received initiation signal; receiving an encrypted restore authorization response from the authorization device in response to the request for authorization; decrypting, if encrypted, the received restore authorization message; verifying the restore authorization message; and restoring the settings on the network connected device if the restore authorization message was verified.
