Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for authenticating data being transferred via a digital transfer system. SOLUTION: The method comprises a step of determining at least two coding values for at least several data before transferred, each of the coding values being determined using the key of a coding algorithm, and a step of outputting at least two coding values together with the data.
