摘要:
随着Internet和多媒体技术的飞速发展,多媒体通信成为人们进行信息交流的重要手段,信息的安全和保密显得越来越重要,促进了多媒体信息、图像信息和声音信息的加密研究。信息隐藏和信息安全技术越来越重要,成为大家研究的一个重要课题。这里提出了一种以混沌二值序列为基础的图像加密算法,改进了灰度差置乱度算法来评价二值图像加密效果,最后对混沌序列对初始条件的敏感性、相邻像素差置乱度、图像加密/解密速度进行了大量测试。实验表明本算法具有加密速度快、加密效果好、安全性高等特点
Abstract:
With the advent of the Intemet and multimedia technology, the multimedia has become more and more important, which makes research multimedia information and picture information and sound information. This paper discusses an image encryption algorithm based on chaotic binary sequences and improves algorithm of gray distance to evaluate the effect of binary image encryption. Experiment on chaotic sequence sensitivity on their initial condition, the scrambling of distance pixels, and the encrypting and de encrypting speed of images. The result shows that the encryption algorithm effect is good and has low computational complexity and high security
