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 Attack on Courtois Toy Cipher [PDF]
IACR Cryptol. ePrint Arch., 2009 . The cube attack has been introduced by Itai Dinur and Adi Shamir [8] as a known plaintext attack on symmetric primitives. The attack has been applied to reduced variants of the stream ciphers Trivium [3, 8] and Grain-128 [2], reduced to three rounds ...

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.

SMT‐based cube attack on round‐reduced Simeck32/64
IET Information Security, 2020 In this study, the authors take advantage of feeding the SMT solver by extra information provided through middle state cube characteristics to introduce a new method which they call SMT-based cube attack, and apply it to improve the success of the solver

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.

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
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.

MILP-aided cube-attack-like cryptanalysis on Keccak Keyed modes [PDF]
Designs, Codes, and Cryptography, 2018 Cube-attack-like cryptanalysis was proposed by Dinur et al. at EUROCRYPT 2015, which recovers the key of Keccak keyed modes in a divide-and-conquer manner. In their attack, one selects cube variables manually, which leads to more key bits involved in the
