Abstract
A method is provided for re-masking from a Boolean mask to an arithmetic mask with a modulus (2m*p), in which m is an integer greater than or equal to zero, and p has at least one prime divisor unequal to 2, so that a carry is generated. The carry is masked or balanced to protect it against intrusion attacks.
