Algebraic Side-Channel Attacks [PDF]
, 2010 In 2002, algebraic attacks using overdefined systems of equations have been proposed as a potentially very powerful cryptanalysis technique against block ciphers. However, although a number of convincing experiments have been performed against certain reduced algorithms, it is not clear whether these attacks can be successfully applied in general and ...

Revisiting the Computation Analysis against Internal Encodings in White-Box Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2023 White-box implementations aim to prevent the key extraction of the cryptographic algorithm even if the attacker has full access to the execution environment. To obfuscate the round functions, Chow et al.

Entropy, 2015 Since Advanced Encryption Standard (AES) in stream modes, such as counter (CTR), output feedback (OFB) and cipher feedback (CFB), can meet most industrial requirements, the range of applications for dedicated stream ciphers is decreasing.

IEEE Access, 2022 In this paper, we propose and evaluate a method for generating key-dependent feedback configurations (KDFC) for $\sigma $ -LFSRs. $\sigma $ -LFSRs with such configurations can be applied to any stream cipher that uses a word-based LFSR.

Algebraic and Slide Attacks on KeeLoq [PDF]
, 2008 KeeLoq is a block cipher used in wireless devices that unlock the doors and alarms in cars manufactured by Chrysler, Daewoo, Fiat, GM, Honda, Jaguar, Toyota, Volvo, Volkswagen, etc [8,9,33,34]. KeeLoq is inexpensive to implement and economical in gate count, yet according to Microchip [33] it should have "a level of security comparable to DES".

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.

Algebraic Attacks on Summation Generators [PDF]
, 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
