haos Based Partial Encryption of SPIHT Coded Color Images
提出了一种基于混沌映射的SPIHT编码彩色图像的部分加密方法。该方案采用基于块-树结构的SPIHT彩色图像编码方法，编码后的图像为二进制位流，然后用分段线性混沌映射产生随机位流与图像编码的重要位异或进行加密。实验表明该方法具有加密位数少，加密效果好，抵抗攻击能力强等优势。
chaos based color image coder incorporating SPIHT compression and partial encryption is presented. The encryption technique is that significant bits of compression bitstream which is generated by block-tree structure based SPIHT of color image XORs a random vector generated by piecewise linear chaotic map. Experiment results show that the proposed method has less bits needed encrypting, high performance and ability to withstand crypanalytic attacks.
