Abstract: | Differential Power Analysis (DPA) is an effective attack method to break the crypto chips and it has been considered to be a threat to security of information system. With analyzing the principle of resist-ing DPA, an available countermeasure based on randomization is proposed in this paper. Time delay is in-serted in the operation process and random number is precharged to the circuit during the delay time, the normal schedule is disturbed and the power is randomized. Following this methodology, a general DPA re-sistance random precharge architecture is proposed and DES algorithm following this architecture is imple-mented. This countermeasure is testified to be efficient to resist DPA. |
