Abstract

1. Method for carrying out an encrypted radio communication between transmit-receive stations, in particular mobile transmit-receive stations, in which method at the start of at least certain transmission procedures a time-dependent item of synchronization and identification information is transmitted between at least two stations from the transmit side to the receive side, characterized in that an item of information (procedure identification) relating to a cipher and exclusively marking the respective transmission procedure is derived from the received identification information and is then immediately compared, with reference to the same cipher, to procedure identifications, retained in a circulating store (SF4, PU), of such previous correct transmission procedures, in that, furthermore, as a function of the result of such a comparison, the information containing this transmission procedure is either rejected as false information or evaluated as genuine information.
