Higher-Order Differential-Linear Cryptanalysis of ChaCha Stream Cipher

IEEE Access
This paper studies the advanced methodologies of differential cryptanalysis with a particular emphasis on higher-order differentials and higher-order differential-linear cryptanalysis, along with their application to the ChaCha stream cipher.

Differential-Linear Cryptanalysis of Reduced Round ChaCha

IACR Transactions on Symmetric Cryptology
ChaCha is a well-known stream cipher that has been used in many network protocols and software. In this paper, we study the security of reduced round ChaCha. First, by considering the differential-linear hull effect, we improve the correlation of a four-

Automated Differential-Linear Cryptanalysis for AND-RX Ciphers

IET Information Security
Differential and linear cryptanalysis are two important methods to evaluate the security of block ciphers. Building on these two methods, differential-linear (DL) cryptanalysis was introduced by Langford and Hellman in 1994. This cryptanalytic method has

Improving the MILP-based Security Evaluation Algorithm against Differential/Linear Cryptanalysis Using A Divide-and-Conquer Approach

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 ...

Rotational Differential-Linear Cryptanalysis Revisited

Journal of Cryptology, 2022
AbstractThe differential-linear attack, combining the power of the two most effective techniques for symmetric-key cryptanalysis, was proposed by Langford and Hellman at CRYPTO 1994. From the exact formula for evaluating the bias of a differential-linear distinguisher (JoC 2017), to the differential-linear connectivity table technique for dealing with ...

A Further Understanding of Differential‐Linear Cryptanalysis [PDF]

Chinese Journal of Electronics, 2020
Differential-linear cryptanalysis has attracted much attention since proposed to attack DES in 1994, and then some generalized theories are developed to complement and unify the method. However, the links between differential-linear cryptanalysis and other important cryptanalysis methods have been still missing. The motivation is to fix the gap.

Generalized differential-linear cryptanalysis of block cipher

Радіотехніка, 2021
Диференціально-лінійний метод криптоаналізу блокових шифрів запропоновано в 1994 р. Він виявляється більш ефективним в порівнянні з (окремо) диференціальним та лінійним методами, проте його наукове обґрунтування залишається предметом подальших досліджень. Відомо декілька публікацій, присвячених формалізації диференціально-лінійного методу та з’ясуванню

Differential-Linear Cryptanalysis [PDF]

, 2007
This paper introduces a new chosen text attack on iterated cryptosystems, such as the Data Encryption Standard (DES). The attack is very efficient for 8-round DES,2 recovering 10 bits of key with 80% probability of success using only 512 chosen plaintexts. The probability of success increases to 95% using 768 chosen plaintexts.

Differential cryptanalysis of full-round ANU-II ultra-lightweight block cipher

International Journal of Distributed Sensor Networks, 2022
Lightweight ciphers are often used as the underlying encryption algorithm in resource-constrained devices. Their cryptographic security is a mandatory goal for ensuring the security of data transmission.

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 ...
