| 摘 要： | 根据矢量数据的特点和混沌映射系统的加密方法,本文提出了一种基于Logistic映射和Chebyshev映射的复合混沌系统。它通过使用迭代状态的周期替换,并输出整数化的混沌映射序列,有效地避免计算机有限精度产生的累计误差。该算法有较强的随机性、抗穷举攻击能力、抵御已知明文攻击能力和较好的时间代价。经过安全性分析,本算法可以较好地用于矢量数据的加密。

| Abstract: | Based on the characteristic of vector data and encryption method of chaos mapping system,this article gave us a composite chaotic system founding on logistic mapping system and Chebyshev mapping system.This system periodically replaces the iterative numerical value and produces integral chaos mapping sequence system.This method would effectively avoid accumulative total error due to finity precision of computer.This arithmetic has the stronger randomicity,the better resisting exhausted attack and known plaintexts attack,and appropriate time cost. |
