speech security
Examples
- The design of gsm digital voice mobile phone based on ambe
数字语音保密通信终端设计 - Simulation of chaotic secure speech communication
混沌语音保密通信仿真实验 - A new secure speech system based on pstn
的新型语音保密系统 - The algorithm have the good one - way property , high sensitivity to initial values and good security due to the intrinsic characteristic of chaotic system and rijndael algorithm . the simulation experiment demonstrates the convenience and good hash performance ; 3 ) a new scheme of digital voice secure communication was proposed based on chaotic modulation without additional synchronization . the modulation sequence generated by chaotic logical mapping was used to encrypt the digital voice signal
混沌系统和rijndael算法的固有特点使该算法具有较好的安全性、对初值有高度的敏感性以及较好的单向性能，并且易于实现，是一种有效的单向hash函数； 3 )研究了一种无需同步的基于混沌调制的数字语音保密通信系统的方案，利用逻辑映射产生混沌调制序列，以该序列作为密码对数字语音进行加密处理，为了更好的隐匿信号特征，混沌调制在小波分解的基础上，对不同的通道使用不同的参数进行，并借鉴混沌掩盖对信息信号进行了限幅处理，使密文完全随机化。
