Vectorized linear approximations for attacks on SNOW 3G
SNOW 3G Stream Cipher 5G Mobile System Security
2019/9/3
SNOW 3G is a stream cipher designed in 2006 by ETSI/SAGE, serving in 3GPP as one of the standard algorithms for data confidentiality and integrity protection. It is also included in the 4G LTE standar...
Linear Approximations of Random Functions and Permutations
random function random permutation multinomial distribution
2019/8/19
The goal of this paper is to investigate the behavior of the ideal cipher under linear cryptanalysis. The motivation of this work is twofold. First, before a practical cipher can be distinguished from...
Linear Cryptanalysis Using Low-bias Linear Approximations
Linear cryptanalysis Multiple linear cryptanalysis Multi-key linear cryptanalysis
2017/3/6
This paper deals with linear approximations having absolute bias smaller than 2−n22−n2 which were previously believed to be unusable for a linear attack. We show how a series of observatio...
New Automatic Search Tool for Impossible Differentials and Zero-Correlation Linear Approximations
Automatic search tool impossible differential zero-correlation linear
2016/7/13
Impossible differential cryptanalysis and zero-correlation linear cryptanalysis are two of the most useful cryptanalysis methods in the field of symmetric ciphers. Until now, there are several automat...
A New Test Statistic for Key Recovery Attacks Using Multiple Linear Approximations

2016/4/26
The log-likelihood ratio (LLR) test statistic has been proposed in the literature for performing statistical analysis of attacks on block ciphers. A limitation of the LLR test statistic is that its ap...

Linear approximation modular additions linear cryptanalysis
2010/10/14
Addition modulo $2^{31}-1$ is a basic arithmetic operation in the stream cipher ZUC. For evaluating ZUC in resistance to linear cryptanalysis, it is necessary to study properties of linear approximati...
Pseudo-Linear Approximations for ARX Ciphers: With Application to Threefish

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...
