MILP-Based Automatic Differential Searches for LEA and HIGHT
MILP model Differential Attack ARX ciphers
2018/11/7
In this paper we use MILP technique for automatic search for differential characteristics of ARX ciphers LEA and HIGHT. We show that the MILP model of the differential property of modular addition wit...
The distinguishing attack on Speck, Simon, Simeck, HIGHT and LEA
secret-key cryptography HIGHT
2018/1/15
The purpose of the work is to estimate the resistance of lightweight block ciphers Speck, Simon, Simeck, HIGHT, LEA to a distinguishing attack. (This attack is a form of cryptanalysis on data encrypte...
HIGHT算法的积分攻击
密码分析 分组密码 积分攻击 HIGHT算法
2016/8/8
对轻量级分组密码算法HIGHT在积分攻击方法下的安全性进行了研究。首先纠正了现有研究成果在构造区分器时的不当之处，重新构造了HIGHT算法的11轮积分区分器，并构造了相应高阶积分扩展下的17轮区分器；其次利用所构造的17轮区分器，结合“时空折中”原理对25轮HIGHT算法进行了积分攻击；最后对攻击算法的复杂度进行了分析，攻击算法需要的数据复杂度为262.92，时间复杂度为266.20，空间复杂度为...
Low Data Complexity Biclique Cryptanalysis of Block Ciphers with Application to Piccolo and HIGHT
Biclique Cryptanlysis Attack Complexity
2014/3/10
In this paper, we present a framework for biclique cryptanalysis of block ciphers with an extremely low data complexity. To that end, we enjoy a new representation of biclique attack. Then an algorith...
Impossible Differential Cryptanalysis of the Lightweight Block Ciphers TEA, XTEA and HIGHT
secret-key cryptography
