移动终端VoLTE语音安全通信方案研究

VoLTE Voice Security Communication Scheme for Mobile Terminals

VoLTE是电信业公认的语音业务目标解决方案,但是针对Vo LTE语音的安全防护方案还处于探索阶段,是研究热点。首先介绍了Vo LTE技术的发展历程及语音通信原理,分析了Vo LTE语音通信安全性上的缺陷,对现有的语音安全技术解决手段也进行了对比评价。最后,为满足金融等特殊用户群体对语音安全的特殊需求,提出了一个Vo LTE语音安全通信的系统性解决方案,该方案具有适应通信技术发展方向,与运营商网络低耦合,支持电信级用户群,端到端安全等特点。

VoLTE is regarded as the aim solution of telecom industry for voice communication. However, the security protetion scheme for VoLTE voice is still in the exploratory stage and is a research hotspot.Firstly the technical background and principle of VoLTE is introduced, then the security deficiency of VoLTE analyzed, and then the current measures to solve the VoLTE voice secure communication also compared and estimated, and finally in order to satisfy the special demand of financial industry users etc, a systemic solution for VoLTE voice secure communication proposed, which has the characteristics of adapting to the development direction of communication technology, low coupling with operator network, supporting Telecom user group, end-to-end security and so on.
