| 摘 要： | 由于混沌同步问题,目前基于混沌的加密数据在网络中传送多采用TCP协议.文中针对网络中传输的数字语音数据,提出了一种数据分块加密算法,这种加密算法可以使用UDP协议传送密文数据,在一定程度上解决了部分密文丢失后接收端的解密问题.算法采用混沌模型库随机加密数据的方法,极大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,编程试验验证了这种算法的可行性.

| Abstract: | Due to chaos synchronization, the TCP protocol is usually adopted to encrypted data transported on networks at present. The group data encryption algorithm is proposed to digital speech codes in this paper. The method uses the UDP protocol to cipher message. It partially solves the problem that some data packages are lost during transportation. This method encryptes 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 amount is great. The algorithm is testified with testing program written by the authors. |
