UAV Intrusion Detection Based on iTransformer for MAVLink Message ID Sequence
This paper introduces a lightweight UAV intrusion detection method utilizing the iTransformer model to analyze MAVLink message ID sequences. It aims to effectively identify normal communication patterns and various types of flooding attacks (Heartbeat Flood, Ping Flood, Request Flood) without relying on message content. The method leverages the iTransformer's sequence modeling capabilities to capture temporal patterns, demonstrating superior detection accuracy (95.7% overall) and robustness compared to traditional approaches, making it suitable for real-time deployment on resource-constrained UAV systems.

Intrusion Detection Output (4 Classes)
The process leverages MAVLink message ID sequences, transforming them through an iTransformer encoder to extract temporal patterns, ultimately classifying communication as normal or one of three flooding attack types.
| Feature | iTransformer | Traditional RNN/LSTM |
|---|---|---|
| Sequence Modeling | Captures global dependencies via self-attention | Limited to historical information, struggles with long sequences |
| Classification Granularity | Accurate 4-class (Normal, Heartbeat, Ping, Request) classification | Often binary (normal/abnormal), lacks fine-grained attack type differentiation |
| Computational Efficiency | Lightweight feature representation (message IDs only), optimized for resource-constrained systems | Often high-dimensional features, computationally demanding |
| Adaptability to Flooding Attacks | Effectively captures abrupt changes and anomalous patterns (e.g., 100% detection for Ping/Request Flood) | Struggles with novel/evolving attack patterns, limited generalization |
This comparison highlights iTransformer's advantages in handling complex temporal data and achieving precise multi-class classification, making it superior for resource-constrained UAV intrusion detection.
