Haraka v2 – Efficient Short-Input Hashing for Post-Quantum Applications

IACR Transactions on Symmetric Cryptology, 2017
Recently, many efficient cryptographic hash function design strategies have been explored, not least because of the SHA-3 competition. These designs are, almost exclusively, geared towards high performance on long inputs.

PQ‐AuthN‐IIoT: A Lightweight, LWE‐Based Postquantum and Privacy‐Preserving Mutual Authentication Scheme for Resource‐Constrained Industrial IoT Systems

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 ...

Polynomial Representations of Weak Inverse Property Quasigroups and Their Role in Cryptographic Primitives

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‐

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 the security risk of pre-image attack on cancelable biometrics

Journal of King Saud University: Computer and Information Sciences
Over the years, a number of biometric template protection schemes, often based on the notion of “cancelable biometrics”, have been proposed. An ideal cancelable biometric algorithm complies with four criteria: irreversibility, revocability, unlinkability,

Functional Graphs and Their Applications in Generic Attacks on Iterated Hash Constructions

IACR Transactions on Symmetric Cryptology, 2018
We provide a survey about generic attacks on cryptographic hash constructions including hash-based message authentication codes and hash combiners. We look into attacks involving iteratively evaluating identical mappings many times.

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 ...

Enhancing Medical Images Security and Efficiency With Adaptive Compressed Sensing and SHA‐3 in Telemedicine

International Journal of Biomedical Imaging, Volume 2025, Issue 1, 2025.
Security issues of telemedicine‐based secure transmission of medical images find a very thin line drawn between diagnostic acceptability and cybersecurity. Partial but imperfect solutions emerge. JPEG2000 and HEVC concentrate only on compression, failing to provide any security consideration.

ArtProtect: Blockchain and NFC‐based anti‐counterfeit system for physical art

IET Blockchain, Volume 4, Issue 4, Page 423-442, December 2024.
An anti‐counterfeiting system for physical art based on Ethereum blockchain and near‐field communication technology is proposed and implemented. The system leverages the use of Ethereum smart contracts and inter‐planetary file system to store artworks’ certificate of authenticity, and display them in a mobile app called ArtProtect.
