中文摘要：

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。

英文摘要：

Based on the information leakage problem of embedded system when performing ZUC algorithm,a new application of side channel attack was introduced by using Fourier Transform in frequency domain.Focused on analy-zing ZUC algorithm in embedded platform,the experiment compared the performance of the side channel attack in time domain with the one in frequency domain.The results show the attack in frequency domain is more efficient and can be applied to more encryption algorithms and embedded systems.
