Abstract
A method for controlling a device includes: sending a command signed by an operator's signature to a server; verifying, in the server, that the operator is authenticated to transmit the command; assigning, in the server, a criticality level and an authorization level to the command; depending on the criticality level and the authorization level, sending an approval request relating to the command to at least one control user; approving or denying the approval request by at least a subset of the at least one control user; sending the denied or approved approval request back to the server; determining, in the server, whether the command was approved by sufficiently many control users based on the criticality level and the authorization level; and sending the command to the device for being carried out by the device in case the command was approved by sufficiently many control users, wherein at last one of the at least one control user and the operator is remote from each other.
