The invention relates to a driver
brake wish sensor (10a, 10b) for a vehicle, having a sensor memory unit (10e, 10f) in which at least one
authentication key (#1 and #2) is stored and a sensor
electronics (10c, 10d) by means of which at least one sensor
signal (16a to 16d) can be output to at least one electric
brake device (12a, 12b) as a sensor
signal (16a to 16d) that is encrypted and / or authenticated with the at least one
authentication key (#1 and #2). Furthermore, the invention relates to an electric
brake device (12a, 12b) for a vehicle for interaction with at least one driver brake wish sensor (10a, 10b), having a memory unit (12e, 12f) in which at least one ID information (ID1 and ID2) about at least one stored
authentication key (#1 and #2) is stored and a
motor control device (12c, 12d) by means of which it can be determined whether at least one
signal provided to the electric brake device (12a, 12b) is encrypted and / or authenticated with the at least one authentication key (#1 and #2) and only then the motor of the electric brake device (12a, 12b) is actuated by means of the
motor control device (12c, 12d) taking into account the at least one signal provided.
