Abstract :
Masking is the general method used to resist Differential Power Analysis. It makes power consumption independent of the intermediate values by XORing all the intermediate values with random values or fixed values. Fixed-value masking is faster and requires less RAM than random-value masking. The present paper proposes a fixed-value mask algorithm for SMS4 to resist power analysis attacks.
