摘　　要：针对无人机无线通信遥测数据帧的结构特点,以及传输实时性和高质量的需求,提出了基于自同步流密码的数据加解密方法。该方法具有加密强度高,错误扩散小,无信息扩散,实现简单等特点。经硬件FPGA实现,证明了该方法的可行性和可靠性。Considering the structure characteristic of telemetry data frames of UAV wireless communication and the requirements of real time and high quality, this paper presents an eneryption method based on self- synchronizing stream cipher. This encryption method is not only higly secure, but can also be easily realized with few error-spreading and no message-spreading. The realization of FPGA shows that the design of the scheme has higher feasibility and trustiness.
