Abstract

In a method for saving the information of a data packet comprising a number of data words (W1 ... We) during the transmission between a transmitting device (2S) and a receiving device (2E), the uncoded data packet is supplemented in a first transformation block (17) by means of a data word (CC) which exhibits a bit pattern which is used uniquely for saving within a predetermined time interval. A supplemented data packet (W1 ...f) is sequentially coded in units of identical length in a device (19) using the cipher-feedback method, the first data word (W1) to be coded being transformed into a unique data word (W1<*>) in a second transformation block (18) before being coded and a coded data word (Yk) being generated by a nonlinear combination of coded data words in the device (19). <IMAGE>
