Abstract: 积分攻击和高阶差分攻击是分组密码的两种重要分析技术.尽管两者的理论基础并不相同,但是它们的攻击过程却十分相似.该文从高阶差分分析的视角来解释AES和Rijndael-256的积分区分器,证明高阶差分分析对此类算法同样有很强的分析能力.此外,改进了Rijndael-256的3轮区分器的数据复杂度.最后,给出了SPON-GENT杂凑函数中间置换的14轮零和区分器.
English Abstract: Integral attack and higher-order differential attack are two important techniques to analyze the block ciphers. There are different theoretical foundations for the two attacks, but they operate with similar procedures. In this paper, we expound the integral distinguishers of AES and Rijndael-256 in a higher-order differential cryptanalysis view, and we demonstrate the strong power of the higher-order differential cryptanalysis for the AES-like ciphers. Besides, the data complexity of the three-round distinguisher of Rijndael-256 is improved. We give a fourteen-round zero-sum distinguisher for the inner permutation of SPONGENT hash function at last.
