针对嵌入式设备在执行ZUC加密运算过程中的侧信道信息泄露问题,提出了一种基于傅里叶变换的侧信道频域攻击。以嵌入式平台上的ZUC加密运算设计实现为分析目标,进行侧信道时域攻击和频域攻击的对比实验。实验结果表明,侧信道频域攻击远比时域攻击更高效,且适用于其他加密算法及多种设计平台。
Aiming at the leakage of side channel information during the implementation of ZUC encryption in embedded devices, a side channel frequency domain attack based on Fourier transform is proposed. Based on the embedded platform ZUC encryption operation design and implementation for the analysis of the target, side-channel time-domain attacks and frequency domain comparative experiments. Experimental results show that side-channel frequency domain attacks are far more efficient than time-domain attacks and are applicable to other encryption algorithms and various design platforms.
