Real-Time Intrusion Detection Based on Decision Fusion in Industrial Control Systems

Industrial control systems (ICSs) are becoming increasingly interconnected as the rapid convergence of information technology (IT) and operation technology (OT) networks, and meanwhile massive attack surfaces have been exposed. However, traditional intrusion detection systems (IDSs) are difficult to be directly deployed in ICSs due to the hard real-time requirement and rare patching chance. Besides, the design of effective and practical IDSs is hampered by the lack of benchmarking ICS cybersecurity datasets. To bridge the gaps, this paper makes the first attempt by open-sourcing the developed ICS cybersecurity datasets and proposing a decision fusion based real-time IDS. Firstly, we design a customized cybersecurity dataset in a full-hardware and high-fidelity platform, including 7 types of cyber threats tailored for ICSs. The collected dataset includes network traffic, sensor readings, actuator status, and system parameters, providing the state-of-the-art benchmark dataset for ICSs consisting of cross-layer characteristics. Furthermore, we design an online decision fusion-based IDS by strategically integrating 4 widely-used machine learning models. The proposed IDS is deployed on a real-time running ethanol distillation, surpassing the performance of single detection models in terms of precision and F1-score, which substantially enhances intrusion detection accuracy and cybersecurity of ICS. © 2023 IEEE.

Floating edge bands in the Bernevig-Hughes-Zhang model with altermagnetism

Physical Review B 2025年第4期111卷 045106-045106页

Floating edge bands (FEB) have been identified in systems such as obstructed atomic insulators and layered nonsymmorphic semimetals, attracting considerable interest recently. Here we demonstrate that FEB can arise in a simplified model incorporating altermagnetism. By enhancing the Bernevig-Hughes-Zhang model on a square lattice with additional altermagnetic and Zeeman fields perpendicular to the two-dimensional plane, we uncover the emergence of FEB that are distinct from the bulk bands across the entire Brillouin zone and over broad parameter regimes. We calculate topological phase diagrams, highlighting the strong topological properties characterized by the Chern number and the weak topological properties marked by the winding number. Furthermore, we provide analytical results of the energy spectrum and the wave functions of the FEB. We also study the robustness of the FEB, showcasing its resilience against various perturbations such as geometric rotation, energy spectrum asymmetry, and spin coupling. Our findings advance our understanding of FEB and may pave new avenues for further exploration of topological phases in quantum materials.

We propose a no-reference (NR) stereoscopic video quality assessment (SVQA) model based on Tchebichef moment in this paper. Specifically, we extract keyframes according to mutual information between adjacent frames, and then the extracted keyframes are segmented to patches to calculate low-order Tchebichef moments. Since the strong description ability of Tchebichef moment, and different order of Tchebichef moment can represent independent features with minimal information redundancy, we extract statistical features of Tchebichef moment on computed patches as spatial features. Considering the influence of distortions in spatiotemporal domain to video quality, we use the three-dimensional derivative of Gaussian filters to calculate the spatiotemporal energy responses and extract statistical features from the responses as spatiotemporal features. Finally, we combine the spatial and spatiotemporal features to predict the quality of stereoscopic videos. The proposed model is evaluated on the NAMA3DS1-COSPAD1, SVQA and Waterloo IVC phase I databases. The experimental results show that the proposed model achieved competitive performance as compared with existing SVQA models. © 2022 SPIE.
