| 摘 要： | 结合混沌序列易生成性、对初始条件敏感性、可完全重现性等特点,给出了一种基于混沌映射的土家织锦图案数字加密算法。首先对原始图案进行离散小波变换（DWT）,变换的矩阵奇行与Logistic映射产生的二值序列异或,偶行与Hybrid映射产生的二值序列异或,然后对产生的新矩阵进行DWT逆变换,即得到加密的织锦图案。实验结果表明,本文算法具有较高的安全性和较好的加密效果。

| Abstract: | We discusse the digital image encryption algorithm on Tujia brocade by chaos sequence theory.Firstly,the origin image is transformed by discrete wavelet transformation(DWT),and the odd-line of the changed matrix operated with binary sequences of Logistic mapping by xor operation,and its even-line operated with binary sequences of Hybrid mapping.Then,the new encryption image is transformed by inverse discrete wavelet transformation(IDWT).The experimental results show that the algorithm is more safety and bet... |
