With the rapid development of the low-altitude economy
security threats facing Unmanned Aerial Vehicle (UAV) networks have increased
and traditional intrusion detection methods are difficult to deploy directly on UAV terminals. To address this problem
a lightweight intrusion detection method for UAV networks based on hybrid knowledge distillation was proposed. This method adopted the serial combination of Bidirectional Gated Recurrent Unit and Transformer to construct a high-performance teacher model
and then used a hybrid knowledge distillation strategy to obtain a lightweight intrusion detection student model for UAV networks with high detection performance. Experimental results on the UAV-NIDD dataset show that
while the number of parameters and model size of the student model are both reduced by approximately 98% compared with those of the teacher model
the student model still achieves a macro-average F1 score of 0.9616 and an inference latency of only 1.198 ms on the Raspberry Pi.
