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 Attacks against Some Arithmetization-Oriented Primitives [PDF]
IACR Transactions on Symmetric Cryptology, 2022 Recent advanced Zero-Knowledge protocols, along with other high-level constructions such as Multi-Party Computations (MPC), have highlighted the need for a new type of symmetric primitives that are not optimized for speed on the usual platforms (desktop

Improvement and evaluation for algebraic fault attacks on PRESENT [PDF]
Tongxin xuebao, 2016 An enhanced algebraic fault analysis on PRESENT was proposed.Algebraic cryptanalysis was introduced to build the algebraic equations for both the target cipher and faults.The equation set of PRESENT was built reversely in order to accelerate the solving ...

Algebraic Adversarial Attacks on Integrated Gradients [PDF]
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.

High Order Side-Channel Security for Elliptic-Curve Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Elliptic-curve implementations protected with state-of-the-art countermeasures against side-channel attacks might still be vulnerable to advanced attacks that recover secret information from a single leakage trace.

Cryptanalysis of ARX-based White-box Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2023 At CRYPTO’22, Ranea, Vandersmissen, and Preneel proposed a new way to design white-box implementations of ARX-based ciphers using so-called implicit functions and quadratic-affine encodings. They suggest the Speck block-cipher as an example target.

Algebraic Attacks Galore! [PDF]
Groups – Complexity – Cryptology, 2009 Summary: This is the first in a two-part survey of current techniques in algebraic cryptanalysis. After introducing the basic setup of algebraic attacks and discussing several attack scenarios for symmetric cryptosystems, public key cryptosystems, and stream ciphers, we discuss a number of individual methods. The XL, XSL, and MutantXL attacks are based

Algebraic Attacks on Combiners with Memory [PDF]
, 2003 Recently, algebraic attacks were proposed to attack several cryptosystems, e.g. AES, LILI-128 and Toyocrypt. This paper extends the use of algebraic attacks to combiners with memory. A (k,l)-combiner consists of k parallel linear feedback shift registers (LFSRs), and the nonlinear filtering is done via a finite automaton with k input bits and l memory ...

Algebraic Description and Simultaneous Linear Approximations of Addition in Snow 2.0. [PDF]
, 2008 In this paper we analyse the algebraic properties over the field GF(2) of the addition modulo 2pn. We look at implicit quadratic equations describing this operation, and at probabilistic conditional linear equations.
