An Efficient Signature Scheme From Supersingular Elliptic Curve Isogenies
Since supersingular elliptic curve isogenies are one of the several candidate sources of hardness for building post-quantum cryptographic primitives, the research of efficient signature schemes based on them is still a hot topic.

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

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 ...

Directed acyclic graph (DAG)‐based blockchain is a promising paradigm of a blockchain system. During DAG‐based consensus processes, nodes generate blocks in parallel, as well as voting YES on the previous blocks. It makes the DAG‐based blockchain a performance advantage in terms of confirmation delay and transaction throughput.

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

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.

Forensic analysis and evaluation of file‐wiping applications in Android OS
Abstract Anti‐forensics refers to techniques designed to obstruct the discovery of evidence in digital forensic investigations. File‐wiping is one of the anti‐forensic techniques that make data recovery impossible by overwriting data with specific patterns. This technique poses significant challenges to investigators.

Forensic detection of medical image manipulation using PACS and DICOM artifacts
Abstract With the digitization of medical information, illegal activities such as medical crimes and insurance fraud through tampering have increased. Medical images are particularly vulnerable due to their nature as soft copies and their transmission over networks.
