Abstract

Abstract: With the development of digital image enciphering techniques，there appeared a lot of methods including those based on Arnold transformation and affine transformation and those based on theories of Hilbert curve，knight-tour problem，Gray code，etc.This paper presents a new image encryption method which based on Monte Carlo random number，and evaluates the effectiveness of the proposed approach by applying it to some images.The experimental results indicate that the new method has visually better encryption effect.

Key words: image encryption, Monte Carlo method, random number

摘要： 随着图像加密技术的发展，出现了各种各样的加密方法，其中有基于Arnold变换、仿射变换、Hilbert曲线、幻方、骑士巡游、Gray码、混沌序列和基于频域的置乱加密技术。讨论了Monte Carlo随机数的性质，构造了一种新的基于Monte Carlo随机数的图像加密算法。实验结果表明该方法计算简单，运行速度快，并具有一定的安全性。
