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).

Cryptanalysis of S-DES [PDF]

, 2002
This paper describes an effort to attack S-DES using differential cryptanalysis and linear cryptanalysis. S-DES is a reduced version of the Data Encryption Standard (DES). It also includes a discussion on the subject of cryptology and a literature survey

Differential Cryptanalysis of REDOC III

, 2007
: REDOC III is a recently-developed block encryption algorithm. This paper describes an attack using differential cryptanalysis that can determine most of the key with about 2 20 chosen plaintexts and 2 30 bytes of storage.

Differential and Linear Cryptanalysis using Mixed-Integer Linear Programming

, 2011
Differential and linear cryptanalysis are two of the most powerful techniques to analyze symmetric-key primitives. For modern ciphers, resistance against these attacks is therefore a mandatory design criterion. In this paper, we propose a novel technique

Security Evaluation against Differential Cryptanalysis for Block Cipher Structures [PDF]

, 2011
Estimating immunity against differential and linear cryptanalysis is essential in designing secure block ciphers. A practical measure to achieve it is to find the minimal number of active S-boxes, or a lower bound for this minimal number.

Improving Differential-Neural Cryptanalysis

IACR Communications in Cryptology
Our first objective is to enhance the capabilities of differential-neural distinguishers by applying more deep-learning techniques, focusing on handling more rounds and improving accuracy. Inspired by the Inception Block in GoogLeNet, we adopted a design that uses multiple parallel convolutional layers with varying kernel sizes before the residual

Enhancing the DATF Technique in Differential-Linear Cryptanalysis [PDF]

Differential-linear cryptanalysis was introduced by Langford and Hellman at CRYPTO\u2794 and has been an important cryptanalysis method against symmetric-key primitives.

AES analysis and its differential cryptanalysis

, 2012
Desde seu estabelecimento como novo padrão de cifragem com chave simétrica, o algoritmo AES tem sido um objetivo importante para várias técnicas de criptoanálise, muitas dessas explorando versões com rodadas reduzidas e buscando encontrar novas fraquezas.
