| 摘 要： | 提出了一种基于一元四次迭代系统的混沌序列生成方法。数值实验和分析结果表明，在一定参数范围内，该迭代系统生成的混沌序列具有良好的相关特性，其动力学行为比Logistic系统更为复杂，所生成的序列应用于计算机信息隐藏与保密通讯方面将具有密钥复杂、安全性更高的优势。

| Abstract: | A generation method of chaotic sequence by a kind of iteration system is proposed.The relative numerical experiment shows that in a certain parameter range,the chaotic sequence has good correlation property and the dynamical characteristic of this iteration system is more complex than Logistic map.The produced preface row applies to conceal with keeping secret in the information and communication will have the higher advantage in safety and complicacy. |
