In a method and circuit configuration for non-linear linkage of two binary words, a first method step is performed by shifting a first binary word to the right by a number of places associated with the first method step, and adding the unchanged first binary word thereto. N--2 further method steps are performed by shifting an outcome of addition of a preceding method step to the right by one place and by a number of places in respective method steps, and adding the unchanged first binary word thereto. A final method step is performed by shifting the outcome of the addition of the preceding method step to the right by one place and by a number of places associated with the final method step. A second binary word is split into n sub-binary words, and the numbers of places associated with the various method steps each correspond to one sub-binary word.
