摘要
差分密码分析和线性密码分析是分组密码分析中应用最广泛的技术。随着差分-线性密码分析的出现,一大批派生出来的密码分析方法表现出了很好的攻击效果。文中首先介绍了这两种密码分析方法的原理,然后推广到双线性密码分析。由于双线性密码分析攻击Feistel结构的密码特别有效,所以在某些场合,由差分密码分析和双线性密码分析结合成的差分-双线性密码分析具有比差分-线性密码分析更好的攻击效果。
Differential cryptanalysis and linear cryptanalysis are the most widely used techniques for block ciphers cryptanalysis. With the emergence of Differential-Linear Cryptanalysis,lots of advace methods for cryptanalysis have accuredt.In this paper, their principles are described,and then an extension of linear cryptanalysis called bilinear cryptanalysis is presented. Finally,a combination called differential-bilinear cryptanalysis is proposed,which is of good performance in same condition.
