Algebraic Attacks and Decomposition of Boolean Functions [PDF]
Lecture Notes in Computer Science, 2004 Algebraic attacks on LFSR-based stream ciphers recover the secret key by solving an overdefined system of multivariate algebraic equations. They exploit multivariate relations involving key bits and output bits and become very efficient if such relations of low degrees may be found.

Algebraic Attacks on Summation Generators [PDF]
Lecture Notes in Computer Science, 2004 We apply the algebraic attacks on stream ciphers with memories to the summation generator. For a summation generator that uses n LFSRs, an algebraic equation relating the key stream bits and LFSR output bits can be made to be of degree less than or equal to \(^{\lceil\log_2 n \rceil}\) using ⌈log2 n ⌉ + 1 consecutive key stream bits. This is much lower

Extreme Algebraic Attacks [PDF]
IACR Cryptol. ePrint Arch.When designing filter functions in Linear Feedback Shift Registers (LFSR) based stream ciphers, algebraic criteria of Boolean functions such as the Algebraic Immunity (AI) become key characteristics because they guarantee the security of ciphers against the powerful algebraic attacks.

Algebraic adversarial attacks on explainability models
Machine Learning. EngineeringClassical adversarial attacks are phrased as a constrained optimisation problem. Despite the efficacy of a constrained optimisation approach to adversarial attacks, one cannot trace how an adversarial point was generated.

Improving Fast Algebraic Attacks [PDF]
Lecture Notes in Computer Science, 2004 An algebraic attack is a method for cryptanalysis which is based on finding and solving a system of nonlinear equations. Recently, algebraic attacks where found helpful in cryptanalysing LFSR-based stream ciphers. The efficiency of these attacks greatly depends on the degree of the nonlinear equations.

Comparative Study of Algebraic Attacks
IARJSET, 2016 Cryptographic schemes have an algebraic structure and can be described as multivariate polynomial equations. Even though algebra is the default tool in the cryptanalysis of asymmetric cryptosystems, there has been recently an increase in interest in the use of algebraic cryptanalysis techniques in the analysis of symmetric cryptosystems. The basic idea

Algebraic Adversarial Attacks on Integrated Gradients
2024 International Conference on Machine Learning and Cybernetics (ICMLC)Adversarial attacks on explainability models have drastic consequences when explanations are used to understand the reasoning of neural networks in safety critical systems. Path methods are one such class of attribution methods susceptible to adversarial attacks. Adversarial learning is typically phrased as a constrained optimisation problem.
