摘要

摘要: 该文对八阵图(ESF)算法抵抗不可能差分密码分析和线性密码分析的能力进行了研究。ESF算法是一种具有Feistel结构的轻量级分组密码算法，它的轮函数为代换置换(SP)结构。该文首先用新的不可能差分区分器分析了12轮ESF算法，随后用线性密码分析的方法分析了9轮ESF算法。计算得出12轮不可能差分分析的数据复杂度大约为O(2⁶⁷)，时间复杂度约为O(2^110.7)，而9轮线性密码分析的数据复杂度仅为O(2³⁵)，时间复杂度不大于O(2^15.6)。结果表明ESF算法足够抵抗不可能差分密码分析，而抵抗线性密码分析的能力相对较弱。

Abstract: The ability of Eight-Sided Fortress (ESF) algorithm to resist impossible differential cryptanalysis and linear cryptanalysis is studied in this paper. The ESF algorithm is a lightweight block cipher algorithm with Feistel structure, and its round function is Substitution-Permutation(SP) structure. Firstly, 12 rounds of ESF algorithm is analyzed in this paper by a new impossible differential distinguisher, and then 9 rounds of ESF algorithm is analyzed by linear cryptanalysis. It is calculated that the data complexity of 12 rounds of impossible differential analysis is about O(2⁶⁷), and the time complexity is about O(2^110.7), while the data complexity of 9 rounds of linear cryptanalysis is only O(2³⁵), and the time complexity is no more than O(2^15.6). The results show that ESF algorithm is able to resist impossible differential cryptanalysis, while its ability to resist linear cryptanalysis is relatively weak.
