A White-Box Masking Scheme Resisting Computational and Algebraic Attacks
Transactions on Cryptographic Hardware and Embedded Systems, 2021 White-box cryptography attempts to protect cryptographic secrets in pure software implementations. Due to their high utility, white-box cryptosystems (WBC) are deployed by the industry even though the security of these constructions is not well defined ...

Security analysis of an encryption scheme based on nonpositional polynomial notations
Open Engineering, 2016 The aim of the research was to conduct a cryptographic analysis of an encryption scheme developed on the basis of nonpositional polynomial notations to estimate the algorithm strength. Nonpositional polynomial notations (NPNs) are residue number systems (

Using Linearizing Sets to Solve Multivariate Quadratic Equations in Algebraic Cryptanalysis
IEEE Access, 2023 In this paper we describe a class of cryptographic guess-and-determine attacks which is based on the notion of a linearizing set. A linearizing set-based attack is applied to a system of Multivariate Quadratic equations (MQ) over $GF(2)$ field, which ...

Algebraic Collision Attacks on Keccak
IACR Transactions on Symmetric Cryptology, 2021 In this paper, we analyze the collision resistance of the two smallest versions of Keccak which have a width of 200 and 400 bits respectively. We show that algebraic and linearization techniques can serve collision cryptanalysis by using some interesting

Toward A More Efficient Gröbner-based Algebraic Cryptanalysis [PDF]
, 2019 In this paper, we propose a new method to launch a more efficient algebraic cryptanalysis. Algebraic cryptanalysis aims at finding the secret key of a cipher by solving a collection of polynomial equations that describe the internal structure of the ...

Generation of Nonlinear Substitutions by Simulated Annealing Algorithm
Information, 2023 The problem of nonlinear substitution generation (S-boxes) is investigated in many related works in symmetric key cryptography. In particular, the strength of symmetric ciphers to linear cryptanalysis is directly related to the nonlinearity of ...

Improved Algebraic Cryptanalysis of the Reduced-Round Advanced Encryption Standard [PDF]
, 2011 As we know Cryptology is divided into two parts: “Cryptography” and “Cryptanalysis”. Since block ciphers can be deployed in many different applications, so we focus on Advanced Encryption Standard (AES) which is the successor of Data Encryption Standard
