Airborne data loading safety and efficiency improvement method and device and medium

The invention discloses an airborne data loading safety and efficiency improvement method and device and a medium, which are based on a TFTP Option extension mechanism, are combined with an ARINC615A protocol, and add the functions of network security, reliable transmission, high-speed distribution, error control, network transfer and the like for the data loading process by adding field options, so that the data loading efficiency is improved. The problems that data transmission based on the TFTP protocol is low in transmission efficiency, poor in safety performance, free of integrity check measures and poor in network applicability are solved. 本发明公开了一种机载数据加载安全与效率改进方法、设备及介质，基于TFTP Option扩展机制，结合ARINC615A协议，通过增加字段选项，为数据加载过程增加网络安保、可靠传输、高速分发、差错控制、网络转移等功能，解决了基于TFTP协议的数据传输所存在的传输效率低、安全性能弱、无完整性检查措施以及网络适用性差的问题。
