Boosting Differential-Linear Cryptanalysis of ChaCha7 with MILP

IACR Transactions on Symmetric Cryptology, 2023
In this paper, we present an improved differential-linear cryptanalysis of the ChaCha stream cipher. Our main contributions are new differential-linear distinguishers that we were able to build thanks to the following improvements: a) we considered a ...

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 ...

A New Method for Generating High Non-linearity S-Boxes [PDF]

Radioengineering, 2010
Substitution boxes are important parts in many block and stream ciphers. The emergence of a range of crypto-attacks has led to the development of criteria for repelling such attacks.

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 ...

Blocking Linear Cryptanalysis Attacks Found on Cryptographic Algorithms Used on Internet of Thing Based on the Novel Approaches of Using Galois Field (GF (2³²)) and High Irreducible Polynomials

Applied Sciences, 2023
Attacks on the Internet of Things (IoT) are not highly considered during the design and implementation. The prioritization is making profits and supplying services to clients. Most cryptographic algorithms that are commonly used on the IoT are vulnerable
