摘要

由于数字混沌受计算机精度的限制,混沌序列的性质呈现短周期。针对数字混沌现象,分析了数字混沌的相似短周期,提出了一种新的数字混沌密钥序列发生器。同时,详细介绍了离散余弦变换(DCT)压缩和小波压缩方法,并对它们的不同性能进行了比较。最后,本文选择较好的压缩图像,然后使用新的混沌序列对压缩图像进行加密。

Similar-short Periodicity Analysis and Application in Image Compression Encryption of Digital Chaos
As digital chaos is affected by the limited precision of computer, chaotic sequence properties present short periodicity. For the phenomenon of digital chaos, the paper analyzes similar-short periodicity of digital chaos and puts forward a novel generator of digital chaos key sequence. Meanwhile, we detail the DCT (Discrete Cosine Transformation) compression and Wavelet compression method, and then make comparison for their different performances. Finally, this paper selects the better compressed image, and then uses new chaotic sequence to encrypt the compressed image.
