New Conditional Cube Attack on Keccak Keyed Modes [PDF]
IACR Transactions on Symmetric Cryptology, 2019 The conditional cube attack on round-reduced Keccak keyed modes was proposed by Huang et al. at EUROCRYPT 2017. In their attack, a conditional cube variable was introduced, whose diffusion was significantly reduced by certain key bit conditions.

Extensions of the Cube Attack Based on Low Degree Annihilators [PDF]
, 2009 At Crypto 2008, Shamir introduced a new algebraic attack called the cube attack, which allows us to solve black-box polynomials if we are able to tweak the inputs by varying an initialization vector. In a stream cipher setting where the filter function is known, we can extend it to the cube attack with annihilators: By applying the cube attack to ...

Cube-Attack-Like Cryptanalysis of Round-Reduced Keccak Using MILP [PDF]
IACR Transactions on Symmetric Cryptology, 2018 Cube-attack-like cryptanalysis on round-reduced Keccak was proposed by Dinur et al. at EUROCRYPT 2015. It recovers the key through two phases: the preprocessing phase for precomputing a look-up table and online phase for querying the output and getting ...

Key‐dependent side‐channel cube attack on CRAFT [PDF]
ETRI Journal, 2021 CRAFT is a tweakable block cipher introduced in 2019 that aims to provide strong protection against differential fault analysis. In this paper, we show that CRAFT is vulnerable to side‐channel cube attacks.

Cube Attacks with Elimination Strategy: Key Recovery Attacks on Trivium
IACR Transactions on Symmetric CryptologyIn this paper, we present a novel framework for cube attacks named cube attacks with elimination strategy. The core idea is to find specific key conditions and cubes such that their superpolies under these key conditions can be efficiently computed.

Cube-like Attack on Round-Reduced Initialization of Ketje Sr [PDF]
IACR Transactions on Symmetric Cryptology, 2017 This paper studies the Keccak-based authenticated encryption (AE) scheme Ketje Sr against cube-like attacks. Ketje is one of the remaining 16 candidates of third round CAESAR competition, whose primary recommendation is Ketje Sr.

A New Practical Cube Attack via Recovering Numerous Superpolys [PDF]
IACR Transactions on Symmetric CryptologyCube attack is one of the most powerful approaches for recovering keys of stream ciphers. Practical cube attacks generate several superpolys first and solve the system constructed by these superpolys afterward.

Differential-Linear Cryptanalysis and Cube Attacks on ChiLow
IACR Transactions on Symmetric CryptologyChiLow is a family of tweakable block ciphers specifically designed for embedded code encryption, proposed at EUROCRYPT 2025. Its novel nested tweakkey schedule and a variant of the χ function significantly enhance latency and energy efficiency.

Breaking Grain-128 with Dynamic Cube Attacks [PDF]
, 2011 We present a new variant of cube attacks called a dynamic cube attack. Whereas standard cube attacks [4] find the key by solving a system of linear equations in the key bits, the new attack recovers the secret key by exploiting distinguishers obtained from cube testers.
