The embodiment of the invention discloses a flight plan verification method and device based on a hash algorithm. The main purpose is to accurately verify an error or a tampered flight plan in the flight plan. According to a main technical scheme, the method comprises the steps that a data receiver receives to-be-verified data sent by a data sender, the to-be-verified data comprises an original flight plan message and a verification field, and the verification field is a first hash value of the original flight plan message; the data receiver calculates and receives the flight plan message to obtain a second hash value; the first hash value is compared with the second hash value; if the first hash value is consistent with the second hash value, that the original flight plan message is transmitted without errors is determined; if the first hash value is inconsistent with the second hash value, that an error occurs in the original flight plan message transmission is determined.
本发明实施例公开了一种基于哈希算法的飞行计划校验方法及装置,主要目的在于准确校验飞行计划中的错误或篡改的飞行计划,主要技术方案包括:数据接收方接收数据发送方发送的待校验数据,所述待校验数据中包含原始飞行计划报文及校验字段,所述校验字段为所述原始飞行计划报文的第一哈希值;数据接收方计算接收到飞行计划报文,得到第二哈希值;将所述第一哈希值与所述第二哈希值进行比对;若所述第一哈希值与所述第二哈希值一致,则确定所述原始飞行计划报文无误传输;若所述第一哈希值与所述第二哈希值不一致,则确定所述原始飞行计划报文传输中出现错误。
