A Novel Efficient Pairing-Free CP-ABE Based on Elliptic Curve Cryptography for IoT

open access: yesIEEE Access, 2018
Ciphertext-policy attribute-based encryption (CP-ABE) is a promising cryptographic technique that integrates data encryption with access control for ensuring data security in IoT systems.

Efficient and secure pairing-free certificateless directed signature scheme

open access: yesJournal of King Saud University: Computer and Information Sciences, 2021
In an ordinary signature scheme any one can verify the validity of a signature produced by the signer. But public verifiability of signatures is not desirable in some applications where the signed message is sensitive to the signature receiver, for ...

A bilinear pairing based secure data aggregation scheme for WSNs [PDF]

open access: yes, 2019
End to end secure data aggregation scheme for wireless sensor networks that are based on public key cryptography generally use elliptic curves. However elliptic curve based protocols require messages to be mapped to elliptic curves before performing any ...

Full‐scale Shaking Table Tests on a 10‐story Steel Moment‐resisting Frame Building with Buckling‐restrained Braces

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In February 2023, a comprehensive series of shaking table tests were conducted at the E‐Defense facility, the world's largest three‐dimensional earthquake simulator, on a full‐scale 10‐story steel moment‐resisting frame supplemented with BRBs.

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

open access: yesEnergy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

High Efficiency NIR Luminescence Beyond 900 nm Through Promoting Cr3+ Pair Generation in Sr3Zr2O7 Layered Perovskite

open access: yesLaser &Photonics Reviews, EarlyView.
A Cr3+/La3+ codoped Sr3Zr2O7 NIR phosphor showing luminescence at ∼960 nm with high IQE/EQE (92.4%/57.5%) and good thermal stability was developed. La3+ stabilizes Cr3+ and induces Cr3+ pairs, enabling efficient blue‐to‐NIR conversion for underwater wireless optical communication.

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces
