Revisit Division Property Based Cube Attacks: Key-Recovery or Distinguishing Attacks?
Division property cube attacks MILP Trivium
2019/4/16
Cube attacks are an important type of key recovery attacks against stream ciphers. In particular, it is shown to be powerful against Trivium-like ciphers. Traditional cube attacks are experimental att...
Deterministic Cube Attacks: A New Method to Recover Superpolies in Practice
Trivium cube attacks key recovery attack
2018/11/12
Cube attacks are an important type of key recovery attacks against NFSR-based cryptosystems. The key step in cube attacks closely related to key recovery is recovering superpolies. However, in the pre...
Correlation Cube Attacks: From Weak-Key Distinguisher to Key Recovery
cryptanalysis cube attack stream cipher
2018/3/7
In this paper, we describe a new variant of cube attacks called correlation cube attack. The new attack recovers the secret key of a cryptosystem by exploiting conditional correlation properties betwe...
A New Framework for Finding Nonlinear Superpolies in Cube Attacks against Trivium-Like Ciphers
Cube attacks Linearity tests Quadracity tests
2018/3/6
In this paper, we study experimental cube attacks against Trivium-like ciphers and we focus on improving nonlinear superpolies recovery. We first present a general framework in cube attacks to test no...
Improved Division Property Based Cube Attacks Exploiting Low Degree Property of Superpoly
Cube attack Division property MILP
2017/11/10
We apply our technique to stream cipher TRIVIUM and KREYVIUM. For TRIVIUM, benefited from our techniques, we, for the first time, can recover the superpoly of 833-rounds with cube dimension 73, and co...
New MILP Modeling: Improved Conditional Cube Attacks to Keccak-based Constructions
Keccak SHA-3 KMAC
2017/10/30
In this paper, we provide a new MILP modeling to find better/optimal choices of conditional cubes. These choices generally find new or improved attacks against the keyed constructions based on Keccak ...
Improved Conditional Cube Attacks on Keccak Keyed Modes with MILP Method
MILP Conditional Cube Attack Keccak Keyed Mode
2017/8/29
Conditional cube attack is an efficient key-recovery attack on Keccak keyed modes proposed by Huang et al. at EUROCRYPT 2017. By assigning bit conditions, the diffusion of a conditional cube variable ...
Cube Attacks on Non-Blackbox Polynomials Based on Division Property
Cube attack Stream cipher Division property
2017/4/11
The cube attack is one of powerful cryptanalytic techniques and is especially powerful against stream ciphers. Since we need to analyze the complicated structure of a stream cipher in the cube attack,...
Investigating Cube Attacks on the Authenticated Encryption Stream Cipher ACORN
CAESAR Authenticated Encryption Cube Attack
2016/12/12
The cube attack is an algebraic attack that allows an adversary to extract low degree polynomial equations from the targeted cryptographic primitive. This work applies the cube attack to a reduced rou...
Practical Complexity Cube Attacks on Round-Reduced Keccak Sponge Function
Keccak SHA-3 sponge function
2016/1/23
In this paper we mount the cube attack on the Keccak sponge function. The cube attack, formally introduced in 2008, is an algebraic technique applicable to cryptographic primitives whose output can ...
Cube Attacks and Cube-attack-like Cryptanalysis on the Round-reduced Keccak Sponge Function
Keccak SHA-3 sponge function
2016/1/7
In this paper, we comprehensively study the resistance of keyed variants of SHA-3 (Keccak) against algebraic attacks. This analysis covers a wide range of key recovery, MAC forgery and other types of ...
Improving Key Recovery to 784 and 799 rounds of Trivium using Optimized Cube Attacks
Trivium Cube attacks Cryptanalysis Moebius Transform
2015/12/31
Dinur and Shamir have described cube attacks at EUROCRYPT ’09 and they have
shown how efficient they are on the stream cipher Trivium up to 767 rounds. These attacks have
been extended to distinguis...
A New Model for Error-Tolerant Side-Channel Cube Attacks
Side-channel attack Cube attack Decoding
2015/12/30
Side-channel cube attacks are a class of leakage attacks on block ciphers in which the attacker is assumed to have access to some leaked information on the internal state of the cipher as well as the ...
Comparison of cube attacks over different vector spaces
Cube/AIDA attack Trivium Linearity testing
2015/12/23
We generalise the cube attack of Dinur and Shamir (and the
similar AIDA attack of Vielhaber) to a more general higher order differentiation
attack, by summing over an arbitrary subspace of the space...

2012/3/29
The paper presents several improved side channel cube attacks on PRESENT based on single bit leakage model. Compared with the previous study of Yang et al in CANS 2009 [30], based on the same model of...
