Abstract The invention relates to a method for processing a binary data item (D), comprising a step of calculating cyclic redundancy check code for the data item by means of a generator polynomial (PC), in which the step of calculating the cyclic redundancy check code comprises steps consisting in: masking the data item with a random binary mask (R2) that is a multiple of the generator polynomial, and generating the cyclic redundancy check code for the data item from the masked data item (D2), the masking process consisting in adding the random binary mask (R2) to the binary data item.
