摘　　要：作为安全高效空中交通管理的重要前提,飞行计划在传输过程中的正确解析至关重要。针对飞行计划传输安全问题,提出了一种基于默克尔树的飞行计划校验算法。构建了批量飞行计划的默克尔树,随批量飞行计划一起发送给接收方;通过比对原始批量报文与接收批量报文的默克尔树,接收方可快速校验大量飞行计划数据,及时定位错误报文,从而提高了飞行计划传输的准确性和安全性。As the premise of safe and efficient air traffic management,correct analysis of flight plan in the transmission process is crucial.Aimed at the transmission safety problem of flight plans,a flight plan verification algorithm based on Merkle tree is proposed.A Merkle tree the batch flight plan is constructed,and it is sent to the receiver along with the flight plan.By comparing the received original batch message with the Merkle tree of the batch message,the receiver can quickly verify the large amount of flight plan data and locate the error message in time.Thus,the transmission accuracy and safety of flight plans can be enhanced.
