摘要
混沌映射具有对初始条件的敏感性、良好的随机性、相关性和复杂性等特性。基于此提出了一种快速、安全的图像混沌置乱算法,实验表明,该算法达到了很好的效果。尤其在大型图像数据库的应用中,该算法在保证安全性的前提下,能在极短的时间内对大量图像进行置乱与恢复。
Chaos mapping is sensitive to the initial condition, random, correlative and complex. Based on that, presents a rapid and safe algorithm of image scrambling which has satisfying effect. Especially, in the image database application, this algorithm can scramble and unscramble many images in short time.
