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.

An Improved Algebraic Attack on Hamsi-256 [PDF]
, 2011 Hamsi is one of the 14 second-stage candidates in NIST's SHA-3 competition. The only previous attack on this hash function was a very marginal attack on its 256-bit version published by Thomas Fuhr at Asiacrypt 2010, which is better than generic attacks only for very short messages of fewer than 100 32-bit blocks, and is only 26 times faster than a ...

RAFA: Redundancies-assisted Algebraic Fault Analysis and its implementation on SPN block ciphers
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Algebraic Fault Analysis (AFA) is a cryptanalysis for block ciphers proposed by Courtois et al., which incorporates algebraic cryptanalysis to overcome the complexity of manual analysis within the context of Differential Fault Analysis (DFA).

Experimental study and modelling of abrasive water jet cutting of aluminum alloy 2024 [PDF]
Journal of Engineering Science and Military Technologies, 2019 Block ciphers cryptanalysis is serious challenge specially with the existing of the powerful block ciphers that require massive number of plaintext-ciphertext pairs to perform a successful attack. Algebraic attack is superior among different attack types

New Low-Memory Algebraic Attacks on LowMC in the Picnic Setting
IACR Transactions on Symmetric Cryptology, 2022 The security of the post-quantum signature scheme Picnic is highly related to the difficulty of recovering the secret key of LowMC from a single plaintext-ciphertext pair.

An Algebraic Attack Against McEliece-like Cryptosystems Based on BCH Codes [PDF]
, 2023 We present an algebraic attack on a McEliece-like scheme based on BCH codes (BCH-McEliece), where the Goppa code is replaced by a suitably permuted BCH code.
