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.

Kite attack: reshaping the cube attack for a flexible GPU-based maxterm search
Journal of Cryptographic Engineering, 2019 Dinur and Shamir’s cube attack has attracted significant attention in the literature. Nevertheless, the lack of implementations achieving effective results casts doubts on its practical relevance.

Higher order differentiation over finite fields with applications to generalising the cube attack
Designs, Codes, and Cryptography, 2016 Higher order differentiation was introduced in a cryptographic context by Lai. Several attacks can be viewed in the context of higher order differentiations, amongst them the cube attack of Dinur and Shamir and the AIDA attack of Vielhaber.

Journal of Software, 2012 Dinur和Shamir在2009年欧洲密码年会上提出了立方攻击的密码分析方法.Grain算法是欧洲序列密码工程eSTREAM最终入选的3个面向 硬件实现的流密码算法之一,该算法密钥长度为80比特,初始向量(IV)长度为64比特,算法分为初始化过程和密钥流产生过程,初始化过程空跑160拍. 利用立方攻击方法对Grain算法进行了分析,在选择IV攻击条件下,若算法初始化过程空跑70拍,我们可恢复15比特密钥,并找到了关于另外23比特密 钥的4个线性表达式;若算法初始化过程空跑75拍,我们可恢复1比特密钥 ...

Conditional Cube Attack on Round-Reduced River Keyak [PDF]
Designs, Codes and Cryptography, 2017 This paper evaluates the security level of the River Keyak against the cube-like attack. River Keyak is the only lightweight scheme of the Keccak-permutation-based Authenticated Encryption Cipher Keyak, which is one of the 16 survivors of the 3rd round ...

The Improved Cube Attack on Grain-v1 [PDF]
IACR Cryptol. ePrint Arch., 2013 The crucial problem of cube attack is the selection of cube set, which also being the most time-consuming process. This paper designs a new search algorithm which generates several linear equations through one cube set and applies cube attack to ...

The Cube Attack on Stream Cipher Trivium and Quadraticity Tests [PDF]
Fundamenta Informaticae, 2010 In 2008 I. Dinur and A. Shamir presented a new type of algebraic attack on symmetric ciphers named cube attack. The method has been applied to reduced variants of stream ciphers Trivium and Grain- 128, reduced variants of the block ciphers Serpent and ...

Breaking Grain-128 with Dynamic Cube Attacks [PDF]
, 2011 We present a new variant of cube attacks called a \emph{dynamic cube attack}. Whereas standard cube attacks \cite{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

Algebraic Properties of the Cube Attack [PDF]
IACR Cryptol. ePrint Arch., 2013 Cube attacks can be used to analyse and break cryptographic primitives that have an easy algebraic description. One example for such a primitive is the stream cipher /Trivium.
