摘　　要：将混沌序列和分组密码相结合而产生一种新型混合密码体制,该体制综合了这两种密码体制的优势,具有较高的安全性.通过混沌序列来产生分组密码所需的密钥流,由此克服了分组密码的相关性的缺陷,实现了在不影响传输速度的同时又有较高的算法安全性.The new model brings to a novelty mixed cryptosystem which combines chaos sequence and block ciphers. This system integrates the advantages of the two cryptosystems and has better security. Keys generated from chaos sequence are used for block ciphers, which can conquer the shortcoming that there is correlation among block ciphers. And a better arithmetic security cab be obtained without the limited transmission speed.
