摘要
互联网应用日益广泛,传输图片量及加密要求也越来越高。基于MATLAB软件对置乱加密、混沌加密、灰度变换加密算法进行分析比较,并采用灰度直方图和相邻像素的相关性作为加密效果的衡量标准。实验数据表明,混沌加密算法性能较优。
Now the Internet is increasingly widely used,the transmission of image volume and encryption requirements are increasingly high. Scrambling encryption,chaotic encryption,gray transformation encryption algorithm is studied in this paper and the algorithm is implemented in MATLAB. The correlation between gray histogram and adjacent pixels is adopted as the measurement standard of encryption effect to analyze three algorithms. Experimental data shows that the chaotic encryption algorithm is better performance.
