摘要
首先给出了从Gray-Scott系统中提取8位整型伪随机序列的一种有效算法,接着提出了一种使用随机序列的图像像素位置置乱算法,在此基础上结合像素值改变技术设计了一套有效的图像加密方法.数值模拟及安全性分析说明加密方法有效.
In this paper, a effective method of distilling 8 bit integer random sequence from the Gray-Scott system is given first, then a algorithm of scrambling the plac e of pixel with random sequence is proposed, based on them and combining algorithm of changing the value of pixel a set of image encryption method is designed. The effectiveness of encryption is tested through numerical simulation and safety analysis.
