摘要： 基于ZORRO加密算法轮变换的可迭代特性,对ZORRO加密算法进行代数分析。在4轮差分特征的基础上迭代5次形成20轮的差分特征,并对ZORRO算法实现迭代差分分析,采用简单方程组并将搜集到的数据带入方程组,从而对方程组求解。实验结果表明,该代数分析法的直观性较好,能够有效恢复密钥。

Abstract: This paper analyzes ZORRO with algebraic method in detail according to its iterative characteristic of the round function.The encryption iterates 5 times based on 4-round differential characteristics to form 20-round differential characteristics,and then it uses the algebraic analysis method to analyze the iterative differential characteristics of ZORRO,substitutes the collected data into simple equations,finally tries to solve the equations.Experimental results show that the algebraic method is more intuitive and can recover the key efficiently.
