AI Technical Summary

Technical Problem

Existing drone protocol identification systems cannot accurately distinguish between structural and behavioral differences between different protocols in scenarios involving mixed access of multiple drone brands, complex electromagnetic interference environments, and dynamic protocol expansion. This leads to mismatches in protocol identification results and poses a risk of communication control anomalies.

Method used

By acquiring the communication data packets of the target UAV, features from the physical layer, data link layer, network layer, and application layer are extracted to construct a protocol fingerprint feature vector. The protocol fingerprint similarity is calculated using the weighted cosine similarity algorithm, KL divergence algorithm, and dynamic time warping algorithm. The communication protocol type is identified by combining the protocol classification model, and protocol semantic consistency verification and dynamic sorting are performed in complex scenarios.

Benefits of technology

It improves the accuracy of identifying communication protocols for various types of heterogeneous UAVs, reduces protocol confusion and mismatch, enhances the stability and reliability of communication protocol identification results, and improves the adaptability to protocol variants and dynamically evolving protocols.
