On the Behaviors of Affine Equivalent Sboxes Regarding Differential and Linear Attacks
Anne Canteaut,Joëlle Roué +1 more
TL;DR: This paper investigates the effect of affine transformations of the Sbox on the maximal expected differential probability and linear potential over two rounds of a substitution-permutation network, when the diffusion layer is linear over the finite field defined by the S box alphabet.

Refined analysis of bounds related to linear and differential cryptanalysis for the AES
TL;DR: In this paper, Park et al. showed that the best 2-round upper bounds are not tight, and therefore neither are the corresponding 4-round corresponding upper bounds for T ≥ 4.
Journal Article
The cryptanalysis of the AES : A brief survey
TL;DR: There have been few cryptanalytic advances since standardisation despite the efforts of many researchers, and the most promising new approach to AES cryptanalysis remains speculative, while the most effective attack against reduced-round versions is older than the AES itself.

Linear cryptanalysis method for DES cipher
TL;DR: A new method is introduced for cryptanalysis of DES cipher, which is essentially a known-plaintext attack, that is applicable to an only-ciphertext attack in certain situations.

Differential cryptanalysis of DES-like cryptosystems
Eli Biham,Adi Shamir +1 more
TL;DR: A new type of cryptanalytic attack is developed which can break the reduced variant of DES with eight rounds in a few minutes on a personal computer and can break any reduced variantof DES (with up to 15 rounds) using less than 256 operations and chosen plaintexts.

The Block Cipher Square
TL;DR: A new 128-bit block cipher called Square, which concentrates on the resistance against differential and linear cryptanalysis, and the publication of the resulting cipher for public scrutiny is published.

Provable Security against Differential and Linear Cryptanalysis for the SPN Structure
TL;DR: This work proves that the SPN structure with a maximal diffusion layer provides a provable security against differential cryptanalysis and linear cryptanalysis in the sense that the probability of each differential is bounded by pn, where p (respectively q) is the maximum differential probability of n S-boxes used in the substitution layer.
