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.

A monitoring device for a repair patch that can be placed on or in a wall of an aircraft to repair a defect has a sensor device for detecting properties of the repair patch placed in the wall, an energy supply device for supplying energy at least to the sensor device, and a communication device so as to read out the sensor data. A repair kit that can be placed in or on a wall of an aircraft to repair defects comprises a repair patch for repairing a defect in or on a wall of an aircraft and also comprises a monitoring device. A method for monitoring a repair patch in or on a wall of an aircraft by means of a monitoring device comprises the steps of detecting a measurement phase on the basis of the amount of energy provided by the energy supply device, measuring load parameters in and/or on the repair patch during the measurement phase, and reading out the load parameters.
