Abstract: Differential-algebraic,which combines differential cryptanalysis and algebraic cryptanalysis,is a new cryptanalysis method.Either differential cryptanalysis or algebraic cryptanalysis is one of the most impactful cryptanalysis methods for AES.In this text how differential-algebraic is used in the AES is analyzed and this method is successfully used to attack the 5-round of the AES-256.The result shows that this method is better than the exhaustive search.

Key words: differential-algebraic, differential cryptanalysis, algebraic cryptanalysis, Advanced Encryption Standard(AES)

摘要: 差分-代数攻击是一种新的攻击方法,此方法结合了差分分析和代数攻击的思想。差分分析和代数攻击都是对高级加密标准(AES)最有效的攻击算法之一。对差分-代数如何在AES中应用进行了分析,并成功地应用此方法对5轮AES-256进行了攻击,使之比穷尽攻击更有效。
