端到端IP电话的安全保密系统设计与实现

Design and Implementation of Secure Privacy System in Point to Point IP Telephony

介绍了一种端到端IP电话的语音加密方案.在分析IP电话存在安全问题的基础上,研究并解决了语音加解密和会话密钥安全协商问题,并实现了端到端IP电话的安全保密通信.测试结果表明,其时延、带宽占用和丢包率均达到了IP电话的QoS要求.

This paper describes a design of ciphering voice in Point to Point IP Telephony, based on analyzing the problem of IP telephony security, the cipher voice and the arrange key are researched and solved, and security of point to point IP telephony is implemented . The results of test show that time delay, bandwidth comsumption and the lost probability of system can satisfy the demand of QoS.
