A Provably-Secure Outsourced Revocable Certificateless Signature Scheme Without Bilinear Pairings
IEEE Access, 2018 Certificateless public key cryptosystem (CLPKC) is a desirable cryptographic system because it refrains from both certificate management and key escrow. In CLPKC, how to revoke a misbehaving or compromised user is an important issue.

Security Vulnerabilities of Four Signature Schemes From NTRU Lattices and Pairings
IEEE Access, 2020 Certificateless cryptography solves the certificate management problem in public-key cryptography and the key-escrow problem in identity-based cryptography. Xie et al. proposed a certificateless signature scheme using NTRU lattices.

Advanced Functional Materials, EarlyView.Geometry‐driven design of soft cellular metamaterials is systematically investigated by combining experiments, finite element modeling, and statistical prediction. The study quantifies how unit cell geometry and material properties govern stiffness, instability, densification, and energy absorption.

Advanced Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

Dynamic Searchable Encryption Scheme Based on Identity [PDF]
Jisuanji gongcheng, 2019 Searchable encryption technology saves user’s local storage resources and simplifies user’s search operation.However,most searchable encryption schemes are only static search.Therefore,this paper presents a dynamic searchable encryption scheme based on ...

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Acceleration of Composite Order Bilinear Pairing on Graphics Hardware [PDF]
, 2012 Recently, composite-order bilinear pairing has been shown to be useful in many cryptographic constructions. However, it is time-costly to evaluate. This is because the composite order should be at least 1024bit and, hence, the elliptic curve group order n and base field become too large, rendering the bilinear pairing algorithm itself too slow to be ...
