| 摘 要： | 本文提出了一个基于小波变换的混合加密算法,即先采用小波变换对图像进行压缩,再用改进Zigzag变换对图像进行置乱,最后用混沌序列矩阵对置乱图再进行异或加密.实验结果表明:该算法简单快捷,密钥空间大,密钥敏感性强.

| Abstract: | A hybrid encryption algorithm based on wavelet transform is proposed. The wavelet transform and improved Zigzag transform are used for image compression and image scrambling. The chaotic sequence matrix is used for xor encryption scrambling. The experimental results show that the algorithm is simple and quick. The key space is large and the key sensitivity is strong |
