摘要
设计了随机掩码在ECC加密算法中的应用方法,为了降低加密芯片的功耗和面积,提高运算性能,研究设计了关键步固定值掩码算法,实验证明提出的方法在资源增加非常有限的情况下可以有效抵抗一阶差分功耗攻击.同时,其他加密算法也可参考此关键步固定值掩码算法来高效设计抗功耗攻击加密芯片.
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.
