| 摘 要： | 为了在互连网上实现语音的实时加密传输,论文采用自适应通信环境库(ACE)实现实时传输协议(RTP),设计了基于该协议的实时语音保密通信系统。语音加密采用数据加密算法与混沌加密算法相结合,将分组加密算法应用到实时数据流通信中,动态改变数据包加密密钥,密钥空间大,抗破译能力强。通过在数据报头中传输迭代次数实现密码同步。测试结果表明,实时语音保密通信系统具有良好的实时通信效果和安全性能。

| Abstract: | To transport secretly audio signals on Internet,based on Real-time Transport Protocol(RTP)and Adaptive Communication Environment(ACE),a real time speech security communication system is designed.In the part of encryption,the 3DES is combined with chaotic encryption,and the block encryption algorithm is applied to real time communication.The key of every data package is changed dynamically which has large keys space and strong ability of anti-attacking.Encryption synchronization is realized by transporting the iteration number in data package.Tests show that the system has good performances on communication effects and security. |
