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.

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.

Clinical Judgment to Recognize Acute Brain Ischemia in the Emergency Department

Acta Neurologica Scandinavica, Volume 2026, Issue 1, 2026.
Background Despite the development of scale‐based stroke recognition tools, the accuracy of clinical judgment to detect acute ischemic stroke (AIS) and transient ischemic attack (TIA) is unknown. This study evaluated the real‐world accuracy of stroke physicians′ assessment in AIS/TIA detection before imaging compared with Recognition of Stroke in the ...

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.

Eliminating Centralized Trust in VANETs: A Blockchain‐Assisted SSL‐PUF Authentication and Cross‐Domain Key Agreement Scheme

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.
Vehicular ad hoc networks (VANETs) enable secure vehicle‐to‐vehicle (V2V) and vehicle‐to‐infrastructure (V2I) communications but still rely heavily on centralized trusted authorities, creating scalability limitations, single‐point failures, and increased authentication latency.

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 ...

Lattice Multiauthority Attribute‐Based Signcryption Scheme for Blockchain‐Based Personal Health Record Sharing

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The sharing of personal health records (PHRs) benefits healthcare by improving disease diagnosis, treatment, and early outbreak detection. However, outsourcing PHRs for storage exposes data to risks such as tampering and unauthorized access. Ensuring the security of PHRs is crucial, especially when shared via third‐party servers. A secure sharing model

Preimage Attack on Hashing with Polynomials proposed at ICISC\u2706 [PDF]

, 2006
In this paper, we suggest a preimage attack on Hashing with Polynomials \cite{Shpilrain06b}. The algorithm has $n$-bit hash output and $n$-bit intermediate state. (for example, $n=163$).
