A method is provided for encrypted radio transmission of data telegrams spaced apart in time in a sequence between a transmitter and a receiver of a system, wherein a key is changeable and is cryptologically derived from a current piece of information. The time elapsed between a preceding telegram and the encrypted telegram implementing the desired data transmission is used as the key. The time span results from a value or entry of a parameter present in the system. The duration in the transmitter and the receiver is determinable from a previously transmitted value or entry of a parameter, or derived only in the transmitter and wirelessly transmitted to the receiver for a future telegram. In a motor vehicle tire pressure monitoring system, the transmitted data originate from a tire sensor and are wirelessly transmitted in an encrypted manner to a vehicle body.
