Quantum Rotational Cryptanalysis for Preimage Recovery of Round-Reduced Keccak [PDF]
, 2022 This paper considers the capability of 4-round Keccak-224/256/384/512 against the cryptanlysis involved by the quantum algorithm. In order to effectively find the corresponding rotational number for the rotational counterpart of preimage, we first ...

On stabilizers in finite permutation groups
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract Let G$G$ be a permutation group on the finite set Ω$\Omega$. We prove various results about partitions of Ω$\Omega$ whose stabilizers have good properties. In particular, in every solvable permutation group there is a set‐stabilizer whose orbits have length at most 6, which is best possible and answers two questions of Babai.

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.The rapid expansion of the Industrial Internet of Things (IIoT) presents pressing challenges for secure, efficient, and privacy‐preserving communication among users, sensors, and cloud infrastructures. Existing lightweight authentication schemes, primarily based on classical cryptographic assumptions, are increasingly vulnerable to the emerging threat ...

Journal of Mathematics, Volume 2026, Issue 1, 2026.A connection between cryptography and polynomial functions is extremely significant. Mathematical performance of polynomials helps to enhance the cryptographic primitives, which are trustworthy as well as straightforward representation tools, in everyday use. In this research, explicit topological sequences Qf which correspond to degree‐based, distance‐

Differential-Aided Preimage Attacks On Round-Reduced Keccak
The Computer Journal, 2022 Abstract At FSE 2008, Leurent introduced the preimage attack on MD4 by exploiting differential trails. In this paper, we apply the differential-aided preimage attack to Keccak with the message modification techniques. Instead of directly finding the preimage, we exploit differential characteristics to modify the messages, so that the ...

Preimage and pseudo collision attacks on round-reduced DHA-256 hash function [PDF]
, 2013 A preimage attack on DHA-256 hash function reduced to 37-round and a pseudo collision attack on the func-tion reduced to 39-round were proposed respectively.Based on the meet-in-the-middle attack,the Biclique technique was used to improve the preimage ...

Constructing Efficient Identity‐Based Signatures on Lattices
IET Information Security, Volume 2025, Issue 1, 2025.In this work, we explore the recent developments related to lattice‐based signature and preimage sampling, and specify a compact identity‐based signature (IBS) on an ideal lattice for practical use. Specifically, we first propose an ellipsoid version of the G + G signature scheme (Asiacrypt 2023) that achieves slightly better signature size and higher ...

Low-weight Pseudo Collision Attack on Shabal and Preimage Attack on Reduced Shabal-512 [PDF]
, 2010 This paper studies two types of attacks on the hash function Shabal. The first attack is a low-weight pseudo collision attack on Shabal. Since a pseudo collision attack is trivial for Shabal, we focus on a low-weight pseudo collision attack.
