公众移动通信网络加密语音通信技术研究

公众移动通信网络在给人们日常生活带来便利的同时,开放的网络使得在其上传输的个人隐私和重要商业信息存在泄露的隐患。文中从公众移动通信网络最常使用的传递信息方式——语音通信入手,对基于CS域语音信道和PS域数据信道进行加密语音通信存在的问题进行了分析。同时结合实际测试情况,提出了在这两种信道上实现加密语音通信的方案。

Encrypted Speech Communication Technology in Public Mobile Communication Network

Public mobile communication network brings much convenience to the people＇ s daily life, and its openness may also expose privacy or important business information transmitted through it. starting from speech communication- the most common mode of information transfer in public mobile communication network, the problems existing in encrypted speech communication based on speech channel of CS and data channel of PS are analyzed Meanwhile,in combination with actual tests, the proposals for realizing encrypted speech communication through those two channels are suggested.
