The invention discloses a password mask method for enhancing attack resistance ability. The password mask method for enhancing the attack resistance ability includes an encryption process. The encryption process includes steps: (1) introducing an original random number X, and performing exclusive-or operation on a clear text; (2) performing IP (internet protocol) initial displacement, and then dividing the clear text into an L portion and an R portion, and furthermore introducing random numbers Xy and Xz, generated in the middle process; (3) introducing F functions amended by mask codes, and performing n turns of F function operation; (4) combining the L portion with the R portion, and then performing an FP inverse initial permutation; (5) introducing the original random number X, and performing the exclusive-or operation so as to obtain a cipher text C. The password mask method for enhancing the attack resistance ability can achieve different effects of the mask codes by only using two types of the F functions amended by the mask codes during the whole encryption and decryption process, and only needs to achieve two types of SM-Box, and compared with other schemes with CPA attack resistance, the password mask method for enhancing the attack resistance ability can save a great number of hardware resources and reduce cost on the premise of substantially enhancing differential power attack and related power consumption attack resistance.
