On the Security of LBlock against the Cube Attack and Side Channel Cube Attack [PDF]
In this research, a recently proposed lightweight block cipher LBlock, not tested against the cube attack has been analyzed. 7, 8 and 9 round LBlock have been successfully attacked with complexities of O(210.76), O(211.11) and O(247.00) respectively. For the case of side channel cube attack, full version of LBlock has been attacked using a single bit ...

Correlation Cube Attack Revisited
In this paper, we improve the cube attack by exploiting low-degree factors of the superpoly w.r.t. certain "special" index set of cube (ISoC). This can be viewed as a special case of the correlation cube attack proposed at Eurocrypt 2018, but under our framework more beneficial equations on the key variables can be obtained in the key-recovery phase ...

A Cube Attack on a Reduced-Round Sycon
The cube attack was proposed at the 2009 Eurocrypt. The attack derives linear polynomials for specific output bits of a BlackBox cipher. Cube attacks target recovery keys or secret states. In this paper, we present a cube attack on a 5-round Sycon permutation and a 6-round Sycon permutation with a 320-bit state, whose rate occupies 96 bits, and whose ...

Cube attacks on round-reduced TinyJAMBU
AbstractLightweight cryptography has recently gained importance as the number of Internet of things (IoT) devices connected to Internet grows. Its main goal is to provide cryptographic algorithms that can be run efficiently in resource-limited environments such as IoT.

Dynamic cube attack on Grain-v1 [PDF]
This study presents a dynamic cube attack on the algorithm Grain‐v1 which has resisted all the key‐recovery attacks in the single key model. The dynamic cube attack finds the secret key by using distinguishers obtained from structural weaknesses of a cipher.

Cube Attacks and Cube-Attack-Like Cryptanalysis on the Round-Reduced Keccak Sponge Function [PDF]
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 attacks, breaking up to 9 rounds (out of the full 24) of the Keccak internal permutation much faster than exhaustive search. Moreover, some of our attacks

Fourteen years of cube attacks
Abstract Algebraic Cryptanalysis is a widely used technique that tackles the problem of breaking ciphers mainly relying on the ability to express a cryptosystem as a solvable polynomial system. Each output bit/word can be expressed as a polynomial equation in the cipher’s inputs—namely the key and the plaintext or the initialisation vector ...

Utilizing Probabilistic Linear Equations in Cube Attacks [PDF]
Cube attacks, proposed by Dinur and Shamir at EUROCRYPT 2009, have shown huge power against stream ciphers. In the original cube attacks, a linear system of secret key bits is exploited for key recovery attacks. However, we find a number of equations claimed linear in previous literature actually nonlinear and not fit into the theoretical framework of ...

Cube Attacks on Tweakable Black Box Polynomials [PDF]
Almost any cryptographic scheme can be described by tweakable polynomials over GF (2), which contain both secret variables (e.g., key bits) and public variables (e.g., plaintext bits or IV bits). The cryptanalyst is allowed to tweak the polynomials by choosing arbitrary values for the public variables, and his goal is to solve the resultant system of ...

The Cube Attack on Courtois Toy Cipher [PDF]
The cube attack has been introduced by Dinur and Shamir [8] as a known plaintext attack on symmetric primitives. The attack has been applied to reduced variants of stream ciphers Trivium [3, 8] and Grain-128 [2], a reduced to three rounds variant of the block cipher Serpent [9] and a reduced version of the keyed hash function MD6 [3].
