Abstract

The transmission method provides an at least doubled data transmission, the data message pairs (T1.1, T2) to be transmitted being represented, by means of suitable measures, by statistically mutually independent bit sequences; this is achieved by using a cryptological coding method in at least one of the data sequences generated at the source end. If this is given, the probability that the data messages in each case belonging together are falsified by interfering influences in such a manner that their falsification can no longer be detected by data comparison at the sink end can be considered as being negligibly small. The method according to the invention, in connection with failsafe signal sources (Q) and sinks (S) allows the failsafe data transmission via a non-failsafe data transmission system, the implementation of which can be completely unknown. <IMAGE>
