研究13轮CLEFIA-128算法，在9轮不可能差分攻击的基础上，提出一种未使用白化密钥的不可能差分密码分析方法。猜测每个密钥，筛选满足轮函数中S盒输入输出差分对的数据对。利用轮密钥之间的关系减少密钥猜测量，并使用Early Abort技术降低计算复杂度。计算结果表明，该方法的数据复杂度和时间复杂度分别为2120和2125.5。
针对AES和CLEFIA的改进Cache踪迹驱动攻击
AES CLEFIA 踪迹驱动 Cache
2012/4/13
通过分析“Cache失效”踪迹信息和S盒在Cache中不对齐分布特性，提出了一种改进的AES和CLEFIA踪迹驱动攻击方法。现有攻击大都假定S盒在Cache中对齐分布，针对AES和CLEFIA的第一轮踪迹驱动攻击均不能在有限搜索复杂度内获取第一轮扩展密钥。研究表明，在大多数情况下，S盒在Cache中的分布是不对齐的，通过采集加密中的“Cache失效”踪迹信息，200和50个样本分别经AES第一轮和...
