Differential Cryptanalysis in ARX Ciphers, Applications to LEA
Differential characteristics Nested Monte-Carlo Search ARX ciphers
font style='font-size:12px;'>
2018/11/9
In this paper we focus on differential cryptanalysis dedicated to a particular class of cryptographic algorithms, namely ARX ciphers. We propose a new algorithm inspired by the Nested Monte-Carlo Sear...

2018/11/9
In this paper, we propose a new algorithm inspired by Nested to find a differential path in ARX ciphers. In order to enhance the decision process of our algorithm and to reduce the search space of our...
Efficient Side-Channel Protections of ARX Ciphers
Modular Addition Masking Side-channel Analysis

2017/9/13
Division property is a generalized integral property proposed by Todo at Eurocrypt 2015. Previous tools for automatic searching are mainly based on the Mixed Integer Linear Programming (MILP) method a...
Automatic Search for Differential Trails in ARX Ciphers (Extended Version)
tools for cryptanalysis automatic search
font style='font-size:12px;'>
2014/3/5
We propose a tool for automatic search for differential trails in ARX ciphers. By introducing the concept of a partial difference distribution table (pDDT) we extend Matsui's algorithm, originally pro...
Pseudo-Linear Approximations for ARX Ciphers: With Application to Threefish

font style='font-size:12px;'>
2010/7/13
The operations addition modulo 2^n and exclusive-or have recently been combined to obtain an efficient mechanism for nonlinearity in block cipher design. In this paper, we show that ciphers using this...
