摘要
MD5算法破译过程的解析:分析了MD5算法中逻辑函数的性质,阐述了两种差分的关系,详细论述了差分路径的控制过程。以王小云的研究数据为基础,从手工推算和程序两方面进行了测试和分析,进行了部分修正,进一步说明了控制差分路径的关键点,对Hash函数的破译分析有着重要的作用。
This paper is about the cryptanalysis of deciphering MD5 algorithm.The properties of the logical functions of the MD5 algorithm are analyzed.The relationships of two differential characteristics and the control process are proposed.Based on the research data provided by Wang,the algorithm is partly amended and deeply analyzed from both the manual calculation and the test program.The key points of controlling the differential paths are discussed.In general,this paper plays an important role in analyzing and breaking the Hash functions.
