Towards non-independence of modular additions in searching differential trails of ARX ciphers: new automatic methods with application to SPECK and Chaskey

Haiwen Qin, Baofeng Wu

ARX-based ciphers, constructed by the modular addition, rotation and XOR operations, have been receiving a lot of attention in the design of lightweight symmetric ciphers. For thei…

Correlation Cube Attack Revisited: Improved Cube Search and Superpoly Recovery Techniques

Jianhua Wang, Lu Qin, Baofeng Wu

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…

Towards a conjecture on a special class of matrices over commutative rings of characteristic 2

Baofeng Wu

In this paper, we prove the conjecture posed by Keller and Rosemarin at Eurocrypt 2021 on the nullity of a matrix polynomial of a block matrix with Hadamard type blocks over commut…

A general construction of permutation polynomials of the form $(x^{2^{m}} + x + δ)^{i (2^{m} - 1) + 1} + x$ over $\F_{2^{2m}}$

Libo Wang, Baofeng Wu

Recently, there has been a lot of work on constructions of permutation polynomials of the form $(x^{2^{m}} + x + δ)^{s} + x$ over the finite field $\F_{2^{2m}}$, especially in the case whe…

More characterizations of generalized bent function in odd characteristic, their dual and the gray image

Libo Wang, Baofeng Wu, Zhuojun Liu

In this paper, we further investigate properties of generalized bent Boolean functions from $Z_{p}^{n}$ to $Z_{p^{k}}$ , where $p$ is an odd prime and $k$ is a positive integer. For v…
