摘要： 本文提出一种将混沌与热流密码体制结合的图像加密算法。首先利用一维热流密码体制对二维图像加密改变图像的像素值，然后利用混沌置换重新分布像素值进一步掩盖密文图像的特征，最后对提出的算法进行仿真试验和安全性分析并且设计完成了加解密演示程序。

Abstract: In this paper, an image encryption algorithm based on heat flow cryptosystem and chaos is proposed. At first, in order to change the image pixels, this scheme employs the one-dimensional heat flow cryptosystems to encrypt the two-dimensional image, and then we shuffle the positions of image pixels by chaotic sequences to confuse the relationship between the cipher-image and the plain-image. At the end, we carry out experimental tests with detailed analysis and design demo applets for the encryption and decryption algorithm.
