Abstract: A method for securing a data processing system having a processing unit is disclosed. At least a group of N1 digital words of m1 bits is selected from among the set of M1 digital words. N1 is less than M1. These words are selected in such a way that each selected digital word differs from all the other selected digital words by a number of bits at least equal to an integer p which is at least equal to 2. The group of N1 digital words of m1 bits form at least one group of N1 executable digital instructions. The processing unit is configured to make it capable of executing each instruction of the at least one group of N1 executable digital instructions.
