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。In order to get high quality voice in spite of low - bandwidth, our system uses several kinds of voice compression algorithms, and it realizes the functions of voice activation and jitter compensation. on the other hand, we use some methods to make voice communication safe. the methods includes : filling traffic, encrypting voice datagram with conventional encryption algorithms ; encrypting session key with asymmetric encryption, multiple authentication
為了保證通信鏈路不被分析,系統實現了一個通信量填充器;為了對傳輸中的語音數據包進行加密,系統提供了des 、 idea 、 blowfish和keyfile等各種常規加密方法;為了利用對稱加密的快速性和公開密鑰加密的方便性,系統只對會話密鑰進行公開密鑰加密。In this model, a local voice server is used to compound voice, broadcast voice, receive dual tone multi frequency ( dtmf ) code and perform concurrent working ; in the meantime, some mature internet technologies such as routing, virtual private network ( vpn ) along with thread technology are also used to carry out valid, reliable access to remote database
在這個模型中,用本地的語音服務器進行語音的合成與播放、接收雙音多頻碼和實現并行工作,同時利用internet中成熟的路由及安全加密等技術對異地數據庫進行有效和可靠的訪問,以獲得語音服務所需要的數據。
