Algebraic and Higher-Order Differential Cryptanalysis of Pyjamask-96 [PDF]
IACR Transactions on Symmetric Cryptology, 2020 Cryptographic competitions, like the ongoing NIST call for lightweight cryptography, always provide a thriving research environment, where new interesting ideas are proposed and new cryptographic insights are made. One proposal for this NIST call that is

Higher-Order Differential-Linear Cryptanalysis of ChaCha Stream Cipher [PDF]
IEEE AccessThis 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.

Degree of Composition of Highly Nonlinear Functions and Applications to Higher Order Differential Cryptanalysis [PDF]
International Conference on the Theory and Application of Cryptographic Techniques, 2002 To improve the security of iterated block ciphers, the resistance against linear cryptanalysis has been formulated in terms of provable security which suggests the use of highly nonlinear functions as round functions. Here, we show that some properties of such functions enable to find a new upper bound for the degree of the product of its Boolean ...

Integral Cryptanalysis of Lightweight Block Cipher PIPO
IEEE Access, 2022 PIPO is a lightweight block cipher proposed at ICISC 2020, which has a byte-oriented structure suitable for bit-sliced implementation and allows for efficient higher-order masking implementations.

Influence of the Linear Layer on the Algebraic Degree in SP-Networks
IACR Transactions on Symmetric Cryptology, 2022 We consider SPN schemes, i.e., schemes whose non-linear layer is defined as the parallel application of t ≥ 1 independent S-Boxes over F2n and whose linear layer is defined by the multiplication with a (n · t) × (n · t) matrix over F2.

Commutative Cryptanalysis Made Practical
IACR Transactions on Symmetric Cryptology, 2023 About 20 years ago, Wagner showed that most of the (then) known techniques used in the cryptanalysis of block ciphers were particular cases of what he called commutative diagram cryptanalysis.

IEEE Access, 2021 The cryptanalytic resistance of modern block and stream encryption systems mainly depends on the substitution box (S-box). In this context, the problem is thus to create an S-box with higher value of nonlinearity because this property can provide some ...

Survey and Benchmark of Block Ciphers for Wireless Sensor Networks [PDF]
, 2006 Cryptographic algorithms play an important role in the security architecture of wireless sensor networks (WSNs). Choosing the most storage- and energy-efficient block cipher is essential, due to the facts that these networks are meant to operate without ...

Key-Recovery Attacks on Full Kravatte
IACR Transactions on Symmetric Cryptology, 2018 This paper presents a cryptanalysis of full Kravatte, an instantiation of the Farfalle construction of a pseudorandom function (PRF) with variable input and output length.

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 ...
