On the Security of an Efficient and Robust Certificateless Signature Scheme for IIoT Environments

IEEE Access, 2019
As the progress of digitization in industrial society, large amount of production data are outsourced to the cloud server in order to reduce data management costs. Nevertheless, how to ensure the outsourced data integrality, validity, and availability is

Networks of Security

, 2023
While the idea that securitization is a relational, continuous process is not new, it remains unclear how this reconceptualization can be applied to systematically study the emergence of security threats at scale. To address this problem, this chapter offers an innovative adaptation of Discourse Network Analysis (Leifeld, 2016) to develop a formalized ...

Laser Remelting of a CrMnFeCoNi High‐Entropy Alloy: Effect of Energy Density on Elemental Segregation

Advanced Engineering Materials, EarlyView.
Laser remelting of a CrMnFeCoNi high‐entropy alloy reveals that optimal chemical homogenization occurs between 30 and 40 J·mm−2. Within this range, elemental segregation is reduced by over 30% compared to the as‐cast state. The study establishes this window as a fast, effective alternative to prolonged annealing for achieving uniform elemental ...

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

Securing personal area networks

The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003
We consider the applicability of ID-based cryptography to providing security within a personal area network (PAN). An initialisation process appropriate for use within a PAN is proposed, and a detailed comparison between the ID-based approach and a more conventional PKI (public key infrastructure) approach is given.

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Carbon Nanotube 3D Integrated Circuits: From Design to Applications

Advanced Functional Materials, EarlyView.
As Moore's law approaches its physical limits, carbon nanotube (CNT) 3D integrated circuits (ICs) emerge as a promising alternative due to the miniaturization, high mobility, and low power consumption. CNT 3D ICs in optoelectronics, memory, and monolithic ICs are reviewed while addressing challenges in fabrication, design, and integration.
