The encoding unit comprises a data input for a detailed data stream of input characters and a data output for an outgoing data stream of output characters. A substitution box is provided, in such a way that the input character of the detailed data stream replaces the assigned output character and to produce the outgoing data. A stream consumption box (30) is provided, which is connected with the data input, formed to release the stream flow and at the same time the input character replaces the output character.
