encrypted voice meaning in Chinese

加密口声

It ' s basic principle : before transmitting data , we encrypt message with idea key and sign or encrypt idea key with rsa . when communicating , we encrypt voice payload with idea session key . when finished communications we destroy idea session key
其基本原理是：数据通信之前，用idea算法对消息明文加密，同时用rsa算法对idea密钥进行加密和实现数字签名。通信中，用idea会话密钥加密语音通讯数据。通信结束后，销毁会话密钥。
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
为了保证通信链路不被分析，系统实现了一个通信量填充器；为了对传输中的语音数据包进行加密，系统提供了des 、 idea 、 blowfish和keyfile等各种常规加密方法；为了利用对称加密的快速性和公开密钥加密的方便性，系统只对会话密钥进行公开密钥加密。
