Practical Algebraic Attack on DAGS [PDF]
, 2019 DAGS scheme is a key encapsulation mechanism (KEM) based on quasi-dyadic alternant codes that was submitted to NIST standardization process for a quantum resistant public key algorithm. Recently an algebraic attack was devised by Barelli and Couvreur (Asiacrypt 2018) that efficiently recovers the private key.

Extracting algebraic equations of the 2-key simplified 3-DES for algebraic cryptanalysis [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

Algebraic Attacks on RAIN and AIM Using Equivalent Representations
IACR Transactions on Symmetric Cryptology, 2023 Designing novel symmetric-key primitives for advanced protocols like secure multiparty computation (MPC), fully homomorphic encryption (FHE) and zero-knowledge proof systems (ZK), has been an important research topic in recent years.

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.

Efficient Attack Scheme against SKINNY-64 Based on Algebraic Fault Analysis
Entropy, 2023 Lightweight block ciphers are normally used in low-power resource-constrained environments, while providing reliable and sufficient security. Therefore, it is important to study the security and reliability of lightweight block ciphers.

Algebraic Attacks on RFID Protocols [PDF]
, 2009 This work aims to identify the algebraic problems which enable many attacks on RFID protocols. Toward this goal, three emerging types of attacks on RFID protocols, concerning authentication, untraceability, and secrecy are discussed. We demonstrate the types of attacks by exhibiting previously unpublished vulnerabilities in several protocols and ...

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 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
