Deep learning greatly improves the detection efficiency of abnormal traffic through autonomous learning and effective extraction of data feature information. Among them, Graph Neural Networks (GNN) effectively fit the data features of abnormal traffic by aggregating the features and structural information of network nodes. However, the performance of GNN in the field of industrial Internet of Things (IIoT) is still insufficient. Since the asymmetry of GNN traffic data is greater than that of the traditional Internet, it is necessary to propose a detection method with high detection rate. At present, many algorithms overly emphasize the optimization of graph neural network models, while ignoring the heterogeneity of resources caused by the diversity of devices in IIoT networks, and the different traffic characteristics caused by multi type protocols. Therefore, universal GNN may not be fully applicable. Therefore, a novel intrusion detection framework incorporating graph neural networks is developed for Industrial Internet of Things systems. Design mini-batch sampling to support data parallelism and accelerate the training process in response to the distributed characteristics of the IIoT. Due to the strong real-time characteristics of the industrial IIoT, data packets in concentrated time periods contain a large number of feature attributes, and the high redundancy of features due to the correlation between features. This paper establishes a model temporal correlation and des...
