摘　　要：随着无人机通信技术的发展,保证传输数据的完整性、可靠性愈发关键。鉴于Hash函数单向性与唯一性的特点,将其引入无人机下行链路通信系统中,进而提出了一种基于改进SHA-1的无人机下行链路安全通信方法,该方法通过对分组后无人机待传输数据的消息摘要进行计算,实现对分组数据的认证。仿真结果表明,该方法可以对无人机待传输数据进行有效认证,并且提高了认证系统的时效性。With the development of UAV communication technology,it is more and more important to ensure the integrity and reliability of data transmission.In view of the unidirectionality and uniqueness of Hash function,it is introduced into UAV downlink communication system,and a method of UAV downlink secure communication based on improved SHA-1 is proposed.The method calculates the message digest of UAV data to be transmitted after dividing into groups,and achieves the authentication of grouped data.The simulation results show that the method can effectively authenticate the data to be transmitted by UAV,and improve the timeliness of the authentication system.
