基于超混沌模型的彩色图像自相关加密算法

Color Image Encryption Algorithm Based on Hyper Chaos Model

随着计算机网络的发展和普及,多媒体安全越来越受人们的重视.在这种背景下提出了一种建立在超混沌模型下的自相关图像加密算法.该算法的模型基础为chen混沌的一个变种,这大大扩展了加密算法的秘钥空间,在加密中使用图像自相关加密方式,使得加密算法可以有效的抵抗明文攻击.实验结果表明,该算法具有优良的性能.

With the development and popularization of computer network, the security of multimedia is becoming more and more important. In this paper,a self-related image encryption algorithm based on hy?per chaos model is proposed.The algorithm of the model is a mutation of Chen′s chaotic,which greatly ex?panded the key space of the encryption algorithm.When using use image autocorrelation encryption,the encryption algorithm can effectively resisting plaintext attacks. Experimental results show that this algo?rithm has good performance.
