摘要： LKJ车载数据是LKJ2000（LKJ-15）实现列车控制的基础和进行运行情况分析的依据。随着运行线路、运输机车及行车方式的不同，LKJ数据也不同。采用远程无线网络公网（4G/3G）在进行车地传输和无线数据换装时，存在LKJ数据被篡改、攻击、渗透的可能。为解决当前铁路LKJ数据换装面临的问题及存在的困难，提升数据换装的效率，保障无线数据换装的安全，研究一种具备网络安全防护功能的LKJ无线安全通信装置，具有非常重要的意义。

Abstract: LKJ onboard data is the basis of LKJ 2000(LKJ-15) to realize train control and operation analysis. LKJ data are different with the different running lines, transportation locomotives and train operation modes. LKJ data may be tampered with, attacked and penetrated during vehicle-ground transmission and wireless data reloading using the public wireless network (4G/3G). In order to solve the current problems and difficulties of railway LKJ data reloading, improve the efficiency of data reloading and ensure the security of wireless data reloading, it is of great significance to study a LKJ wireless security communication device with network security protection  function.

Key words: LKJ data, wireless reloading, network security
