不可能差分分析作为差分分析的一种变体,是一种简单有效的密码分析方法,也是目前最常用的密码分析方法之一.该方法一经提出就得到了广泛应用,被用于分析大量的算法和密码结构.尤其是近年来对AES的攻击,得到了一系列非常好的攻击结果,使得不可能差分分析已成为对AES最有效的攻击方法之一.系统介绍了不可能差分分析的原理、常用技巧和攻击方法,并总结了目前的研究现状和已取得的攻击结果.最后,分析了不可能差分攻击的优缺点及其在设计和分析分组密码方面的作用.
Impossible Differential Analysis as a variant of differential analysis is a simple and effective method of cryptanalysis and one of the most commonly used cryptanalysis methods.When it is proposed, it has been widely used to analyze a large number of Algorithm and password structure.Especially in recent years, we have got a series of very good attack results, which makes the impossibility of differential analysis become one of the most effective attack methods to AES.The system introduces the principle of impossibility differential analysis , Common techniques and attack methods, and summarizes the current research status and the results of the attack.Finally, the advantages and disadvantages of impossible differential attacks and their roles in the design and analysis of block ciphers are analyzed.
