%X 摘要： 利用零相关线性分析方法评估Midori64算法的安全性。利用“中间相错”的方法构造了Midori64的6轮零相关线性逼近,在此基础上,对10轮Midori64进行了密钥恢复攻击。该攻击过程的数据复杂度约为262.4个明密文对,计算复杂度为279.35次10轮加密运算。结果表明缩减至10轮的Midori64算法对于零相关线性分析方法是不免疫的。<br>Abstract: The security of Midori64 against zero-correlation linear cryptanalysis is evaluated. By using the “miss-in-the-middle” technique, 6-round zero-correlation linear approximations are constructed. Based on the 6-round distinguisher, key-recovery attack on 10-round Midori is performed. The data complexity is 262.4 plaintexts and the time complexity is 279.35 10-round encryptions. The testing result shows that the Midori reduced to 10-round is not immune to multidimensional zero-correlation linear analysis
