| 英文摘要 |
| With the wide application of networks in control systems, the process of data replay attacks and keeping
the stability of networked control systems is a problem that the researchers must consider. On the basis of establishing a
control system including a control network and a measurement network, a data transmission method between sensor nodes
and controller nodes is proposed. The mathematical model of the networked control system is given. Considering the
presence of the replay attacks to the controller nodes, a real-time anomaly detection method is presented on the basis of
adding the time stamp in the data frame. The strategy of adding digital watermarking and chi-square goodness of fit test
are described in detail. The simulation results show that the detection method of goodness of fit test can detect the replay
attack actions in real time. The method has certain application prospects and popularization values. |
