Network Threat Analysis and Protection Technology of UAV System

With the development of UAV (Unmanned Aerial Vehicle) technology, UAVs have been widely used in the military, industrial, agricultural, commercial and other fields. At the same time, network attacks against UAV systems have become increasingly fierce, bringing great challenges to UAV security. In the setting of the typical application scenarios of UAV, the paper expounds the composition and structure of UVA, analyzes the network security situation , combs and classifies the security threats of UAV in detail from the perspectives of confidentiality, integrity and usability, constructs a model to strengthen the software security, hardware security and communication link security of UAV system, and puts forward safety protection suggestions for UAV system, and provides reference for future UAV system design and network security protection.
