民用通信设备群路加密方法的探讨

The Investigation of Bulk Encryption Method for Commercial Communication Equipment

介绍了信息传输过程中群路加密的意义,分析了战术通信系统中群路加密的工作原理和工作过程,以及战术通信系统和民用通信系统工作流程的异同,推导出了民用通信系统的群路加密方法,即帧同步、对告和本端告警信息的传递与交互方法。该方法实现简单、工作可靠,具有广泛的应用价值。

This paper first describes the significance of bulk encryption during information transmission,analyzes the operating principle and process of bulk encryption in tactical communication system,then the differences of working processes between tactical and commercial communication systems are depicted,and a method of bulk encryption for commercial communication equipment is evolved,i.e.transmission and interaction of frame sync,remote alarm indication and local alarm indication.The method mentioned is easy to realize,reliable for operation,and may be adopted widely in applications.
