| 摘 要： | 本文对Rijndael-256密码进行分析,从比特的层面上寻找平衡性,得到了一个新的3轮积分区分器,该区分器仅需32个明文就可将3轮Rijndael-256与随机置换区分开来,并且所得密文的每一比特都是平衡的.该区分器在已知的mjndael-256积分区分器中所需明文量最少.基于新的区分器,对4至7轮Riindael-...

| Abstract: | Rijndael-256 is analyzed in this paper.We trace the propagation of the plaintexts structure at bit-level to obtain the property,and present a new 3-round distinguisher which needs least chosen plaintexts of all the known integral distinguishers.In this distinguisher,32 chosen plaintexts are encrypted by 3-round cipher,each bit of the cipertext is balanced.Based on the new distinguisher,reduced-round Rijndael-256 are attacked.The paper also analyzes the distinguisher from another point of view,which can also... |
