Multidimensional Linear Cryptanalysis of Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 This paper presents new generic attacks on Feistel ciphers that incorporate the key addition at the input of the non-invertible round function only.

Links between differential and linear cryptanalysis [PDF]
, 2006 Linear cryptanalysis, introduced in 1994 by Matsui, will most certainly open-up the way to new attack methods which may be made more efficient when compared or combined with differential cryptanalysis. This paper exhibits new relations between linear and

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.

IACR Transactions on Symmetric Cryptology, 2020 In recent years, Mixed Integer Linear Programming (MILP) has been widely used in cryptanalysis of symmetric-key primitives. For differential and linear cryptanalysis, MILP can be used to solve two kinds of problems: calculation of the minimum number of ...

Non-Linear Approximations in Linear Cryptanalysis [PDF]
, 1996 By considering the role of non-linear approximatioris in linear cryptanalysis we obtain a generalization of Matsui's linear cryptanalytic techniques. This approach allows Ihe cryptanalyst greater flexibility in mounting a linear cryptanalytic attack and we demonstrate the effectiveness of our non-linear techniques with some simple attacks on LOK191 ...

Linear Cryptanalysis of Reduced-Round SIMON Using Super Rounds
IACR Cryptology ePrint Archive, 2020 We present attacks on 21-rounds of Simon 32/64, 21-rounds of Simon 48/96, 25-rounds of Simon 64/128, 35-rounds of Simon 96/144 and 43-rounds of Simon 128/256, often with direct recovery of the full master key without repeating the attack over multiple ...

Cryptanalysis of Round-Reduced Fantomas, Robin and iSCREAM
Cryptography, 2019 In this work, we focus on LS-design ciphers Fantomas, Robin, and iSCREAM. LS-designs are a family of bitslice ciphers aimed at efficient masked implementations against side-channel analysis.

On the Security Margin of TinyJAMBU with Refined Differential and Linear Cryptanalysis
IACR Cryptology ePrint Archive, 2020 This paper presents the first third-party security analysis of TinyJAMBU, which is one of 32 second-round candidates in NIST’s lightweight cryptography standardization process. TinyJAMBU adopts an NLFSR based keyed-permutation that computes only a single

On Matsui's linear cryptanalysis [PDF]
, 1995 In [9] Matsui introduced a new method of cryptanalysis, called Linear Cryptanalysis. This method was used to attack DES using 247 known plaintexts. In this paper we formalize this method and show that although in the details level this method is quite different from differential cryptanalysis, in the structural level they are very similar. For example,
