Method and device for generating factors of a RSA modulus N with a predetermined portion Nh, the RSA modulus comprising at least two factors. A first prime p is generated; a value Nh that forms a part of modulus N is obtained; a second prime q is generated in an interval dependent from p and Nh so that pq is a RSA modulus that shares Nh; and information enabling the calculation of the modulus/V is outputted.
