A Strongly Unforgeable Certificateless Signature Scheme and Its Application in IoT Environments

open access: yesSensors, 2019
With the widespread application of the Internet of Things (IoT), ensuring communication security for IoT devices is of considerable importance. Since IoT data are vulnerable to eavesdropping, tampering, forgery, and other attacks during an open network ...

MA‐LCPPA: A Multi‐Aggregator Lattice‐Based Conditional Privacy‐Preserving Authentication Scheme for Scalable and Quantum‐Secure VANETs

open access: yesIET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...

On the security of joint signature and encryption revisited

open access: yesJournal of Mathematical Cryptology, 2016
In 2002, An et al. [1] proposed three generic conversions of signcryption, ℰ⁢t⁢𝒮${\mathcal{E}t\mathcal{S}}$, 𝒮⁢t⁢ℰ${\mathcal{S}t\mathcal{E}}$ and 𝒞⁢t⁢ℰ&𝒮${\mathcal{C}t\mathcal{E}\&\mathcal{S}}$ from the primitive encryption scheme and signature scheme ...

Rapid Nasal Breathing as a Biometric Trigger: High‐Accuracy Electroencephalogram‐Based Authentication for Clinical Applications

open access: yesThe Clinical Respiratory Journal, Volume 20, Issue 1, January 2026.
Our study demonstrates rapid nasal breathing‐evoked EEG signals enable high‐accuracy (98.3%) biometric authentication via a hybrid ResNet‐Swin Transformer model. This noninvasive approach eliminates external stimuli, offering secure patient identification for critical respiratory care settings, such as ventilator access and continuous monitoring ...

Lattice-based Proxy Signature Scheme in the Standard Model

open access: yes工程科学与技术, 2014
:The provably secure public-key cryptosystems in the standard model are more practical, but the provably secure lattice-based proxy signature schemes in the standard model have not been constructed up to now.

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

open access: yesJournal 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 ...

Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 7, July 2025.
Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...

Reconsidering Forgiveness and Unforgiveness: A Call for a More Nuanced Understanding of Unforgiveness

open access: yesSocial and Personality Psychology Compass
ABSTRACT This essay explores the complex nature of forgiveness and unforgiveness as responses to wrongdoing. Traditionally, forgiveness has been framed as a process that promotes psychological and relational well‐being, whereas unforgiveness is often viewed as harmful.
