Abstract: The present invention relates to a method for transmission of a digital signal from a first unit (2), operating according to a transmission mode, to a second unit (3), operating according to a reception mode, through a transmission channel (4), said first unit carrying out the following steps: (a) division of said digital signal in data blocks, each data block comprising n elementary units each having a set time duration; and (b) permutation of elementary unit order of each block on the basis of a permutation instruction, said permutation instruction being selected from a permutation instruction table calculated beforehand, by generation of an address by a pseudo-random address generator (11) by a synchronism seed (12); and said second unit (3) carrying out the following step: (c) permutation of order of said elementary units of each data block received on the basis of a permutation instruction corresponding to the permutation instruction applied to each one of said data blocks during said step (b) from said first unit (2), said permutation instruction being selected from a permutation instruction table calculated beforehand corresponding to the table contained in said first unit (2), following the generation of an address by a pseudo-random address generator (11) by the synchrony seed (12) corresponding to the synchrony seed (12) used by said pseudo-random address generator (11). The present invention also relates for a system (1) for carrying out said method.
