摘要: 针对纵向重用型高级加密标准(AES)一阶掩码加密运算过程中的侧信道信息泄露问题,提出一种基于功率谱的频域二阶相关性能量分析攻击方法。以智能卡上软实现的AES一阶掩码加密算法为研究对象,对其脆弱点进行分析并加以实验,研究更高效的高阶能量分析攻击方法。侧信道二阶时域攻击和二阶频域攻击实验的对比结果表明,基于功率谱的二阶频域攻击曲线对齐效果更好,数据处理时间复杂度和数据存储空间具有明显优势,攻击更高效,且此攻击方法适用于一阶掩码密码算法的攻击。

Abstract: For the information leakage problem in the first-order mask encryption operation of vertically-reused mask in Advanced Encryption Standard(AES),this paper proposes an attack method based on power spectrum of second-order Correlation Power Analysis(CPA) in frequency domain.With the soft realization of AES first-order mask encryption algorithm in smartcard as the research object,the paper analyzes the weak points of the algorithm and conducts experiments,in order to get a more efficient high-order attack method.This paper compares the second-order CPA experiment in time domain with the one in frequency domain.The result shows that the second-order attack in frequency domain presents a better alignment effect,and has more obvious advantages in data processing complexity,data storage space,and attacks than in time domain.Furthermore,this attack method is applicable to other first-order mask cryptographic algorithms.

Key words: Side-channel Attack(SCA), vertically-reused Advanced Encryption Standard(AES), power spectrum, second-order Correlation Power Analysis(CPA), frequency domain attack
