AI Technical Summary

Technical Problem

Data transmission during UAV inspections suffers from several problems, including open channels making them susceptible to eavesdropping, insufficient eavesdropper location capabilities, limited protection mechanisms, high energy consumption, and low optimization efficiency. Existing solutions struggle to provide efficient, low-energy, and secure transmission under the energy-constrained conditions of UAVs.

Method used

A secure data transmission method for drone inspections using 4G private deployment is proposed. By deploying an integrated communication and sensing base station to identify eavesdropping channels, a collaborative physical layer protection system for mission drones and protection drones is constructed. Combined with end-to-end encryption and identity authentication, a cross-layer collaborative dual security mechanism is formed. A joint optimization model is established with secure transmission rate as the optimization objective, and the model is decomposed into sub-problems that are solved iteratively.

Benefits of technology

It effectively resists passive eavesdropping and active attacks, significantly improves security gains, reduces energy consumption, extends battery life, meets real-time requirements, and reduces system complexity and deployment costs.
