摘    要:分析已有的数字图像加密算法之后,提出了一种基于混沌序列的数字图像加密新算法,该算法先将图像数据进行压缩,压缩之后再用混沌序列进行加密,加密后的图像数据保存在文本文件中。实验结果表明,该算法具有可行性,通用性和加密效果好等优点。

关 键 词:混沌序列  图像加密  Logistic映射  图像压缩  文本文件

Abstract:After analyzing some image encryption algorithms, this paper presents a new image encryption algorithm based on chaotic sequences. At first, an image data is compressed, then the compressed data is encrypted based on chaotic sequences and the encrypted data is saved to text file. The experimental results show that the algorithm is feasible, universal and has good encrypt effect.
Keywords:chaotic sequences  image encryption  logistic map  image compression  text file
