It is a critical communication and monitoring technology in the new navigation system, but its protocol does not provide relevant authentication and data encryption, so it is extremely vulnerable to various spoofing attack. Based on the data characteristics, this paper uses the deep learning seq2seq model to reconstruct the ADS-B time series, and the reconstruction error can detect the anomalous ADS-B messages. Extending the feature space of time series enables the model to better capture the time dependence to further improve the effect of anomaly detection. The experimental results show that the proposed method is superior to traditional machine learning methods and time series enrichment can improve detection results. Compared with the existing spoofing attack detection method, the proposed method does not need to change the ADS-B protocol and does not require additional participating nodes or sensors, and has certain adaptability and flexibility.
