摘要:

针对敏感信息保密必要性导致的数据孤岛问题,提出了一种适用于工业信息物理系统(CPS)的安全协作入侵检测系统(PFD-GAN)。具体来说,首先通过融入Wasserstein距离和标签条件,改进外部分类器生成对抗网络(EC-GAN),构建了一种新型半监督入侵检测模型,以产生能够实用的生成数据来增强分类性能。同时,在改进EC-GAN的训练中,融合本地差分隐私技术,防止敏感信息的泄露、保障协作过程的隐私安全。此外,设计了基于去中心化联邦蒸馏的协作方式,允许多个工业CPS共同构建一个综合的入侵检测系统,以识别整个网络系统下的威胁,而无须共享统一的模板模型。对真实工业CPS数据集的实验评估和理论分析表明,PFD-GAN可以在免受隐私泄露风险的同时,高效地检测针对工业CPS的各种类型攻击。

Abstract:

Aiming at the data island problem caused by the imperativeness of confidentiality of sensitive information, a secure and collaborative intrusion detection system (CIDS) for industrial cyber physical systems (CPS) was proposed, called PFD-GAN.Specifically, a novel semi-supervised intrusion detection model was firstly developed by improving external classifier-generative adversarial network (EC-GAN) with Wasserstein distance and label condition, to strengthen the classification performance through the use of synthetic data.Furthermore, local differential privacy (LDP) technology was incorporated into the training process of developed EC-GAN to prevent sensitive information leakage and ensure privacy and security in collaboration.Moreover, a decentralized federated distillation (DFD)-based collaboration was designed, allowing multiple industrial CPS to collectively build a comprehensive intrusion detection system (IDS) to recognize the threats under the entire cyber systems without sharing a uniform template model.Experimental evaluation and theory analysis demonstrate that the proposed PFD-GAN is secure from the threats of privacy leaking and highly effective in detecting various types of attacks on industrial CPS.

Key words: intrusion detection system, cyber physical system, generative adversarial network, local differential privacy, decentralized federated distillation
