中文拼音 [yǔyīnjiāmìjī]
語音加密機
英文
speech encryptor-
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
混沌系統和rijndael演算法的固有特點使該演算法具有較好的安全性、對初值有高度的敏感性以及較好的單向性能，並且易於實現，是一種有效的單向hash函數； 3 ）研究了一種無需同步的基於混沌調制的數字語音保密通信系統的方案，利用邏輯映射產生混沌調制序列，以該序列作為密碼對數字語音進行加密處理，為了更好的隱匿信號特徵，混沌調制在小波分解的基礎上，對不同的通道使用不同的參數進行，並借鑒混沌掩蓋對信息信號進行了限幅處理，使密文完全隨機化。Government : in order to cut administration cost and increase the work efficiency of government, the video conference system has more and more widely used nowadays. video conference systems can help government to increase remote communication, so that to cut meeting and travel cost, improve the decision - making process
政府機關：為了加快信息交流速度，保證政令暢談，同時提高辦公會議質量和效率，召開電視電話會議已經成為各級政府機關普遍推崇的方式，語音圖像數據可同時交互，使溝通及時有效，鼎視通的一系列先進技術更保障了會議的安全保密。In the part of voice encryption, spatiotemporal chaotic system ( ocoml model ) and lfsr are used to generate multidimensional pseudo - random sequence. this sequence has a longer period, better randomicity, passing the verification of fips 140 - 2 security requirements. using the key stream generated by it to encrypt the voice gets a better security
在語音加密方面，本文利用時空混沌系統（單向耦合映象格子模型）與線性移位寄存器產生了高維的偽隨機序列，該序列周期很長，具有更強的隨機性，通過了fips140 - 2的安全性能驗證，利用其作為密鑰流對語音信號進行加密，獲得了更高的保密性。
