Attention Reversal Driven Cross-Model Black-Box Attack on RFFI

Mingye Li, Zhi Chai, Sarkorjon Kurbonov, Hao Wang et autres

Radio Frequency Fingerprint Identification (RFFI) has emerged as a promising secure authentication paradigm for Internet of Things (IoT) security. However, recent evidence suggests that deep-learning-based RFFI systems are critically vulnerable to adversarial attacks. Existing adversarial methodologies predominantly rely on white-box assumptions requiring …

A Certificateless Authentication Scheme Based on Zero-Divisor Graph for IoT

Wei Chen, Zhongkai Dang, Yanzhao Tian

The deployment of the IoT necessitates authentication mechanisms that are both lightweight and secure, particularly for resource-constrained devices. While traditional Public Key Infrastructure (PKI) and Identity-Based Cryptography (IBC) are hindered by certificate management and key escrow issues, early certificateless signature (CLS) schemes …

Research on Electromagnetic Scattering Characteristics of Moving Time-Varying Dusty Plasma Based on Lorentz-SO-FDTD Method

Yong Bo, Xianmin Guo, Qingqing Deng, Wei Chen et autres

This article establishes an electromagnetic scattering model for high-speed moving targets covered by a dusty plasma sheath, utilizing the Bhatnagar-Gross–Krook (BGK) collision model of fully ionized dusty plasma. The proposed Lorentz-shift-operator finite-difference time-domain (Lorentz-SO-FDTD) method is employed to compute the backscatter radar …
