| Abstract: | First,power analysis attacks of elliptic curve cryptographic algorithms are introduced,the random mask in the application of ECC algorithm is proposed and designed,on this basis,a key step fixed-value masking method has proposed and designed in order to reduce the encryption chip's power consumption and area,to improve computing performance.It has been proved that the proposed algorithm can effectively resist the first-order differential power attacks. |
