摘　　要：针对架空输电线路巡检无人机被攻击诱骗劫持易造成航拍图像数据丢失等问题,提出基于现场可编程门阵列(Field Programmable Gate Array,FPGA)的航拍图像在线级加密方法。该方法在无人机端采用FPGA加密模块对航拍图像进行实时在线加密,在地面站或遥控终端侧利用嵌入式安全芯片(Embedded Secure Access Module,ESAM)对回传的航拍图像进行实时在线解密,实现在无人机飞航过程中航拍图像实时在线加/解密,保障专业级架空输电线路无人机线路巡检数据安全。Aiming at the problem of aerial image data loss caused by the attack,deception and hijacking of aerial transmission line inspection drones,an online-level encryption method for aerial images based on Field Programmable Gate Array(FPGA)is proposed.This method uses FPGA encryption module to encrypt aerial images in real time on the drone side,uses embedded secure access module(ESAM)on the ground station or remote control terminal to decrypt the returned aerial images in real time and realizes the real-time online encryption/decryption of aerial images during the flight of the UAV to ensure the safety of the UAV line inspection data of professional overhead transmission lines.
