工业物联网（IIoT）因资源受限设备深度融入关键工业流程，带来显著安全挑战。现有安全方案通常仅在单一网络层应对威胁，依赖昂贵硬件且局限于仿真环境。本文提出博士论文的研究框架与贡献，旨在构建轻量级机器学习（ML）驱动的IIoT安全体系。首先采用Tm-IIoT信任模型与混合式工业物联网（H-IIoT）架构作为基础，提出核心贡献——信任收敛加速（TCA）方法，通过机器学习预测并缓解网络质量下降对信任收敛的影响，在保持对抗行为鲁棒性的同时，将收敛时间缩短最多达28.6%。随后设计基于低成本开源硬件的现实部署架构，支持安全框架的实施与扩展。最后，概述面向多层攻击检测的持续研究，涵盖物理层威胁识别及对抗性机器学习攻击的防御策略。
原文摘要 · Abstract (English)
The Industrial Internet of Things (IIoT) introduces significant security challenges as resource-constrained devices become increasingly integrated into critical industrial processes. Existing security approaches typically address threats at a single network layer, often relying on expensive hardware and remaining confined to simulation environments. In this paper, we present the research framework and contributions of our doctoral thesis, which aims to develop a lightweight, Machine Learning (ML)-based security framework for IIoT environments. We first describe our adoption of the Tm-IIoT trust model and the Hybrid IIoT (H-IIoT) architecture as foundational baselines, then introduce the Trust Convergence Acceleration (TCA) approach, our primary contribution that integrates ML to predict and mitigate the impact of degraded network conditions on trust convergence, achieving up to a 28.6% reduction in convergence time while maintaining robustness against adversarial behaviors. We then propose a real-world deployment architecture based on affordable, open-source hardware, designed to implement and extend the security framework. Finally, we outline our ongoing research toward multi-layer attack detection, including physical-layer threat identification and considerations for robustness against adversarial ML attacks.
