MPC‐Facilitated Adaptive Security Framework for BFT Protocols

IET Information Security, Volume 2026, Issue 1, 2026.
The growing use of blockchain and distributed systems requires Byzantine fault tolerant (BFT) protocols that remain secure under dynamic adversaries. However, existing BFT protocols often rely on static assumptions and lack clear mechanisms to detect and remove malicious or denial‐of‐service (DoS) nodes during execution.

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

IET 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 ...

Attribute-Based Signcryption : Signer Privacy, Strong Unforgeability and IND-CCA2 Security in Adaptive-Predicates Attack [PDF]

, 2014
An Attribute-Based Signcryption (ABSC) is a natural extension of Attribute-Based Encryption (ABE) and Attribute-Based Signature (ABS), where we have the message confidentiality and authenticity together.

Partially blind proxy re-signature scheme with proven security

Tongxin xuebao, 2018
In order to solve the problem of anonymity and controllability of blind proxy re-signature,the concept of partially blind proxy re-signature was introduced by using the idea of partially blind signature.Furthermore,the security definition of partially ...

Strongly Unforgeable and Efficient Proxy Signature Scheme with Fast Revocation Secure in the Standard Model

International Journal of Distributed Sensor Networks, 2016
The existing proxy signature schemes with the proxy revocation function are proven to be malleable and do not possess strong unforgeability. Motivated by these concerns, a new proxy signature scheme with fast revocation is proposed, and it can be proved ...

On the Quantum Security of OCB

IACR Transactions on Symmetric Cryptology, 2022
The OCB mode of operation for block ciphers has three variants, OCB1, OCB2 and OCB3. OCB1 and OCB3 can be used as secure authenticated encryption schemes whereas OCB2 has been shown to be classically insecure (Inoue et al., Crypto 2019).

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

The 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 ...

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 ...
