卫星导航定位服务系统数据传输安全性探究

Probe into data transmission security of satellite navigation and positioning service system

为进一步增强卫星导航定位服务系统数据传输的安全性,提出1种卫星导航位置服务系统基站数据的安全传输方法:使用由北斗导航工程实验室,采用国产芯片及国产加密算法自主研发的数据传输安全模块,在不改变当前卫星导航位置服务系统网络环境的状态下,解决数据传输安全性、可靠性、完整性问题;给出数据传输安全模块的工作原理和技术要点,并分析卫星导航定位服务系统数据传输网络环境;最后对数据传输安全模块进行测试。结果表明,该方法能够完成接收机站端与数据中心端信息的安全传输,实现基站数据的安全传输和受控管理。

In order to further enhance the security of data transmission for satellite navigation and positioning service systems,the paper proposed a secure data transmission method for the basestation of the systems:the data transmission security module independently developed by Beidou Navigation Engineering Laboratory with domestic chips and domestic encryption algorithm was used to solve the security,reliability and integrity of data transmission without changing the current network environment of satellite navigation and positioning service systems;the working principle and technical points of the module were given,and the data transmission network environment of the systems was analyzed;finally the performance of the module was tested.Result showed that the proposed method could accomplish the safe information transmission between the receiver and the data center,which realizes the safe data transmission and controlled management of the basestation.
