Enhancing Differential-Linear Cryptanalysis [PDF]

, 2002
Differential cryptanalysis analyzes ciphers by studying the development of differences during encryption. Linear cryptanalysis is similar but is based on studying approximate linear relations. In 1994, Langford and Hellman showed that both kinds of analysis can be combined together by a technique called differential-linear cryptanalysis, in which the ...

Wave-Shaped Round Functions and Primitive Groups [PDF]

, 2018
Round functions used as building blocks for iterated block ciphers, both in the case of Substitution-Permutation Networks and Feistel Networks, are often obtained as the composition of different layers which provide confusion and diffusion, and key ...

Quantum Differential and Linear Cryptanalysis

IACR Transactions on Symmetric Cryptology, 2016
Quantum computers, that may become available one day, would impact many scientific fields, most notably cryptography since many asymmetric primitives are insecure against an adversary with quantum capabilities.

Differential-Linear Cryptanalysis of Serpent [PDF]

, 2003
Serpent is a 128-bit SP-Network block cipher consisting of 32 rounds with variable key length (up to 256 bits long). It was selected as one of the 5 AES finalists. The best known attack so far is a linear attack on an 11-round reduced variant.

System approach to disparity estimation [PDF]

, 1995
A system approach to disparity estimation using dynamic programming is presented. The four step system can calculate a dense correspondence map between a stereo pair with parallel or nonparallel camera geometry.

Distribusi Difference dari S-Box Berbasis Fungsi Balikan Pada GF(28)

Jurnal Matematika, 2016
Substitution-box (s-box) is a basic component of block cipher which performs a substitution. Two powerful cryptanalysis techniques applied to block ciphers are linear cryptanalysis and differential cryptanalysis.

Cryptanalysis of NBC-128

Dianzi Jishu Yingyong, 2021
NBC is a family of block ciphers using Generalized Feistel structure, designed by Xu Hong et al. There are three block and key sizes,i.e.,128/128, 128/256 and 256/256. A 16-bit Sbox is involved in the cipher as the non-linear component.

Towards Key-recovery-attack Friendly Distinguishers: Application to GIFT-128

IACR Transactions on Symmetric Cryptology, 2021
When analyzing a block cipher, the first step is to search for some valid distinguishers, for example, the differential trails in the differential cryptanalysis and the linear trails in the linear cryptanalysis.
