| 摘 要： | 针对数字语音数据的传输问题，提出一种可用UDP协议传送密文数据的分块加密算法，在一定程度上解决了部分密文丢失后接收端的解密。算法采用混沌模型库随机加密数据的方法，增强了混沌密码序列的随机性，克服了混沌序列加密大数据量数据时的序列周期问题，编程试验验证了该算法的可行性。

| Abstract: | The group data encryption algorithm is proposed for digital speech codes. The method uses the UDP protocol to cipher message. It partially solves the problem that some data packages lost during transportation. This method encrypts message with chaotic sequences which randomly come from chaos database, so randomicity of whole chaotic sequence is enhanced greatly. Further more, it can overcome the disadvantage of short period when data are a great deal. The algorithm is testified with test program written by author. |
