1. A method for authenticating at least one ventilator with at least one remote station, the ventilator being capable of connecting itself via at least one interface to the at least one remote station, wherein the method comprises;
storing at least one authentication file on the ventilator, which authentication file contains at least one signature code of a signing authority, a public keycode of the signing authority is being known to the at least one remote station,
sending the authentication file to the at least one remote station when establishing a connection to the at least one remote station, the remote station checking the signature code of the authentication file using the public keycode as to whether the signature code originates from the signing authority, and
authenticating the ventilator when the at least one remote station recognizes the signature code as originating from the signing authority, and
wherein a connection from the ventilator to the at least one remote station is only established and/or accepted and/or maintained if the at least one remote station recognizes the signature code as originating from the signing authority and the ventilator is authenticated.
