A New Method for Constructing Integral‐Resistance Matrix for 5‐Round AES
IET Information Security, Volume 2025, Issue 1, 2025.A powerful theory for evaluating block ciphers against integral distinguishers was introduced by Hebborn et al. at ASIACRYPT 2021. To show the integral‐resistance property for a block cipher, their core idea is to construct a full‐rank integral‐resistance matrix. However, their method does not work practically for 5‐round AES due to the large S‐box and

A Provably Secure Authentication Protocol Based on PUF and ECC for IoT Cloud‐Edge Environments
IET Information Security, Volume 2025, Issue 1, 2025.The Internet of Things (IoT) cloud model provides an efficient scheme for rapid collection, storage, processing, and analysis of massive node data, and its application has gradually expanded to key areas such as healthcare and transportation. However, the security issues of open channel transmission in IoT still persist. Researchers have proposed a lot

Cryptanalysis on Two Kinds of Number Theoretic Pseudo‐Random Generators Using Coppersmith Method
IET Information Security, Volume 2025, Issue 1, 2025.Pseudo‐random number generator (PRNG) is a type of algorithm that generates a sequence of random numbers using a mathematical formula, which is widely used in computer science, such as simulation, modeling applications, data encryption, et cetera. The efficiency and security of PRNG are closely related to its output bits at each iteration.

Improved Linear Cryptanalysis of SOSEMANUK [PDF]
, 2010 The SOSEMANUK stream cipher is one of the finalists of the eSTREAM project. In this paper, we improve the linear cryptanalysis of SOSEMANUK presented in Asiacrypt 2008. We apply the generalized linear masking technique to SOSEMANUK and derive many linear approximations holding with the correlations of up to 2-25.5.

Best Known Fast Correlation Attack on SNOW 3G Based on a New Insight
IET Information Security, Volume 2025, Issue 1, 2025.The well‐known SNOW 3G stream cipher serves as the core of 3GPP confidentiality and integrity algorithms UEA 2 and UIA2 for universal mobile telecommunications system (UMTS) and long term evolution (LTE) networks. Recently, Gong and Zhang gave two linear approximations of SNOW 3G with correlation 2−20.48, and then proposed a fast correlation attack on ...

Another look at success probability of linear cryptanalysis
Advances in Mathematics of Communications, 2019 This work studies the success probability of key recovery attacks based on using a single linear approximation. Previous works had analysed success probability under different hypotheses on the distributions of correlations for the right and wrong key ...

Security against differential and linear cryptanalysis for general SPT models
Tongxin xuebao, 2012 To use SP network in stream ciphers safely and efficiently,the ability against differential and linear cryptanalysis of SPT models was studied,where S and T denote different layers for substitution,in which compression could be achieved,and P denotes the

Generating Graphs Packed with Paths Estimation of Linear Approximations and Differentials
IACR Transactions on Symmetric Cryptology, 2018 When designing a new symmetric-key primitive, the designer must show resistance to known attacks. Perhaps most prominent amongst these are linear and differential cryptanalysis. However, it is notoriously difficult to accurately demonstrate e.g.

Variants of Differential and Linear Cryptanalysis
International Journal of Computer Applications, 2015 cipher is in vogue due to its requirement for integrity, confidentiality and authentication. Differential and Linear cryptanalysis are the basic techniques on block cipher and till today many cryptanalytic attacks are developed based on these. Each variant of these have different methods to find distinguisher and based on the distinguisher, the method ...
