Zusammenfassung:	In a method for generating a digital key in a first communication device and in a second communication device, the first communication device transmits a first electromagnetic signal to the second communication device, which extracts the digital key from the received first electromagnetic signal. The second communication device transmits a second electromagnetic signal to the first communication device, which likewise extracts the digital key from the received second electromagnetic signal. A direct signal component, transmitted on a direct signal path between the first communication device and the second communication device, of the first electromagnetic signal and of the second electromagnetic signal is attenuated.
