| Abstract: | To carry out the attacks of RSA CMOS(Complementary Metal Oxide Semiconductor) chips,the paper has investigated the theory of the differential power analysis based on the power consumption of cipher chip.And taking the RSA cipher algorithm as goal,the paper has finished the experiment of the differential power analysis attack.The paper proposes a randomized masking method as countermeasure. |
