A Unified Markov Approach to Differential and Linear Cryptanalysis

, 1994
Differential and linear cryptanalysis are two attacks on product ciphers that use approximations of the round function F to derive information about the secret key.

Revisiting the shuffle of generalized Feistel structure

Cybersecurity
The Generalized Feistel Structure ( $$\texttt{GFS}$$ GFS ) is one of the most widely used frameworks in symmetric cipher design. In FES 2010, Suzaki and Minematsu strengthened the cryptanalysis security of $$\texttt{GFS}$$ GFS by searching for shuffles ...

Resistance of Balanced S-boxes to Linear and Differential Cryptanalysis

, 2007
: In this letter, we study the marginal density of the XOR distribution table, and the linear approximation table entries of regular substitution boxes (s-boxes).

Links among impossible differential, integral and zero correlation linear cryptanalysis [PDF]

, 2015
As two important cryptanalytic methods, impossible differential and integral cryptanalysis have attracted much attention in recent years. Although relations among other cryptanalytic approaches have been investigated, the link between these two methods ...

The design of Xoodoo and Xoofff

IACR Transactions on Symmetric Cryptology, 2018
This paper presents Xoodoo, a 48-byte cryptographic permutation with excellent propagation properties. Its design approach is inspired by Keccak-p, while it is dimensioned like Gimli for efficiency on low-end processors.

Multiple differential-zero correlation linear cryptanalysis of reduced-round CAST-256

Journal of Mathematical Cryptology, 2017
CAST-256 (or CAST6) is a symmetric-key block cipher published in June 1998. It was submitted as a candidate for Advanced Encryption Standard (AES). In this paper, we will propose a new chosen text attack, the multiple differential-zero correlation linear

Subspace Trail Cryptanalysis and its Applications to AES

IACR Transactions on Symmetric Cryptology, 2017
We introduce subspace trail cryptanalysis, a generalization of invariant subspace cryptanalysis. With this more generic treatment of subspaces we do no longer rely on specific choices of round constants or subkeys, and the resulting method is as such a ...

Link Between the Differential Cryptanalysis and Linear Approximations over Finite Abelian Groups And Its Applications [PDF]

In recent years, progress in practical applications of multi-party computation (MPC), fully homomorphic encryption (FHE), and zero-knowledge proofs (ZKP) motivates people to explore symmetric-key cryptographic algorithms, as well as corresponding ...

Affine linear cryptanalysis

, 2020
In this paper a new variant of the linear cryptanalysis method for block ciphers is proposed. It is based on the existing method of multidimensional linear cryptanalysis, but offers the option of discarding a whole half-space of linear approximations ...

Substitution-Permutation Networks Resistant to Differential and Linear Cryptanalysis

, 1994
In this paper we examine a class of product ciphers referred to as substitution-permutation networks. We investigate the resistance of these cryptographic networks to two important attacks: differential cryptanalysis and linear cryptanalysis.
