The invention relates to a method for detecting and/or preventing relay attacks. The object is achieved by a method for detecting a relay attack, wherein radio signals at different frequencies are transmitted between a first and a second object and phase measurements and propagation time measurements are performed on these radio signals, and the change in the phase measurements for a change in the frequency is compared with the signal propagation measurements or their change, and, if a predetermined difference or a difference determined from measurements on the radio signals is exceeded, it is assumed that a relay attack is taking place.
