This study introduces a decentralized trajectory planning framework for small unmanned aerial systems that accounts for Remote Identification (RID) location spoofing attacks. By treating RID information as unverified and utilizing physical-layer observations to assess broadcast credibility, the approach enhances safety in multi-aircraft operations. Simulation results show a significant reduction in near mid-air collision events compared to traditional planners that rely on trustworthy RID data, all while ensuring computational efficiency for real-time applications.
Trusting RID data can lead to mid-air collisions, but a new planning framework reduces these risks by treating RID information as suspect.
This work presents a decentralized, spoofing-aware trajectory planning framework for small unmanned aerial systems operating under Remote Identification (RID) location spoofing attacks. Existing planners typically assume RID broadcasts are trustworthy, which can increase the risk of loss of separation and mid-air collisions when spoofing occurs. In contrast, the proposed approach explicitly treats RID information as unverified and incorporates physical-layer observations to assess broadcast credibility. Received signal-strength measurements from neighboring aircraft are used to detect spoofing and probabilistically localize a spoofing agent. The resulting uncertainty is converted into a risk-bounded unsafe region using a chance-constrained formulation and integrated into a per-agent Markov decision process-based planner. This enables real-time, decentralized collision avoidance while preserving mission objectives and scalability. Simulation results in a multi-aircraft package delivery scenario demonstrate reduced near mid-air collision events compared to planners that assume truthful RID data, while maintaining computational efficiency suitable for real-time execution.
