Abstract

An approach for operating at least one touch-sensitive, flat input device of a complete device, the input device being connected via a message-based bus connection to a control device of the complete device, and messages containing touch datasets describing touch data events being transmitted to the control device, which evaluates the messages for input information for an application program implemented by the control device, wherein when a security function in the control device that queries sensitive input information is accessed, the touch datasets are transmitted from the input device to the control apparatus via the bus connection in encrypted form until the associated input process has ended.
