New Integral Distinguisher for Rijndael-256
block cipher integral attack Rijndael-256
font style='font-size:12px;'>
2009/12/29
The known 3-round distinguisher of Rijndael-256 is byte-
oriented and 28 plaintexts are needed to distinguish 3-round Rijndael
from a random permutation. In this paper, we consider the in°uence of

Vortex: A New Family of One Way Hash Functions based on Rijndael Rounds and Carry-less Multiplication
One Way Hash Functions Rijndael Rounds Carry-less Multiplication

2009/6/9
We present Vortex a new family of one way hash functions that can produce message
digests of 224, 256, 384 and 512 bits. The main idea behind the design of these hash
functions is that we use well k...

2000年10月Rijnael被选为高级加密标准(AES),目前对它最有效攻击仍是由设计者提出的Square攻击。Square攻击是利用密码Square特性提出的选择明文攻击,可以对六轮和六轮以下的Rijndael密码进行成功的攻击,攻击六轮Rijndael的所有密钥的计算量为2×272+264,五轮密码的复杂度为3×240+232。该文提出了逆序Square攻击算法,该算法是基于密码Square...
Rijndael算法的代数方程系统改进
密码学 分组密码 代数攻击 Rijndael算法
font style='font-size:12px;'>

该文根据Rijndael算法中S盒的代数表达式,通过合理假设S盒变量,利用各变量之间的关系建立方程,把Rijndael加密算法描述成GF(28)上的一个多变量二次方程系统。该二次方程系统是稀疏的且是超定(Overdefined)的,可以认为恢复Rijndael的密钥等同于求解这个方程系统。与其他描述Rijndael密码的方程系统相比,该文中描述S盒方程的项数与变量更少,因此用XSL(eXtende...

由于Rijndael的S盒的代数表达式是逆函数合成GF(28)上一个q-多项式,该文合理假设S盒的变量并通过讨论各变量之间的关系,把Rijndael用GF(28)上一个多变量二次方程组来表示,使得Rijndael的密钥恢复等同于求解这个方程组.该方程组较Murphy-Robshaw方程组更简单,用XSL技术求解复杂度更低。

The authors analyze the security of Hierocrypt-3(128-bit)
and Hierocrypt-L1(64-bit) designed on the nested SPN(NSPN) structure
against the differential and linear cryptanalysis, and found that they ...
