A Robust Reversible Watermarking Algorithm Resistant to Geometric Attacks Based on Tchebichef Moments

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper presents a robust reversible watermarking algorithm based on Chebyshev moments, employing a two‐stage embedding mechanism. The proposed method leverages image block partitioning to embed the copyright watermark and the reversible watermark into non‐overlapping regions located inside and outside the inscribed circle of the image, respectively.

Blockchain‐Enabled Privacy‐Preserving Access Control for EHRs Sharing With Optimized User and Attribute Revocation

IET Information Security, Volume 2026, Issue 1, 2026.
Electronic health records (EHRs) have become a crucial application in cloud computing environments, necessitating advanced privacy‐preserving access control mechanisms. Ciphertext policy attribute‐based encryption (CP‐ABE) is a widely recognized solution for secure access control in outsourced data environments.

Revisiting the Security of the Lightweight Stream Cipher Draco: New Observation and TMDTO Attacks

IET Information Security, Volume 2026, Issue 1, 2026.
Draco is a lightweight small‐state stream cipher proposed in 2022. It is designed to provide a 128‐bit security level and be provably secure against time‐memory‐data trade‐off (TMDTO) attacks. In this paper, we revisit the security of Draco against TMDTO attacks.

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 ...

Design and Development of a Blockchain‐Enabled Decentralized Framework for Academic Microcredentials

IET Software, Volume 2026, Issue 1, 2026.
Traditional higher education faces significant challenges, including rising costs, inflexibility, and a disconnect from workforce demands, while current credentialing systems are often centralized and vulnerable to fraud. Microcredentials have emerged as a solution, yet they lack integration into formal degree pathways and face issues with recognition ...

A Private Blockchain and IPFS‐Based Secure and Decentralized Framework for People Surveillance via Deep Learning Techniques

IET Software, Volume 2026, Issue 1, 2026.
The modern metropolis essentially demands the use of state‐of‐the‐art, real‐time surveillance systems, which should be reliable, scalable, and respectful of privacy at the same time. Critical shortcomings in traditional architectures are single points of failure, poor scalability, frequent data breaches, and inadequately managed privacy.
