A design for secure radio authorization systems in respect of a discovery of an attack on a radio authorization system, in particular for access restriction systems, for example for securing radio keys, for example for automobiles. The design can be used in simpler systems and can be combined with the numerous known solutions, such as complex enabling signals, that, from a design point of view, are not dependent on the assumption of limited computing power. This object is achieved by a design in which the focus is not on the direct prevention of an attack, but rather on a determination of whether or not a signal is an original signal of the radio authorization system, specifically with reference to the signal and not (only) with reference to the content encoded in the signal, by checking whether a metric of the spectral distribution lies within a predetermined range.
