基于二维时空混沌模型,给出了一种时空混沌二值序列的产生方法,并对其性能进行了分析.结果表明,该种序列消除了相邻点的相关性,改善了统计分布特性,并利用此方法产生的序列对灰度图像进行加密.仿真结果表明,用该方法产生的序列对图像加密后,其相邻像素点的相关性很低,并对其密钥敏感性和统计特性进行了分析,均说明该方法应用于图像加密很有效.

This paper proposed a new image encryption algorithm based on improved coupled map lattices(CML) in order to meet the requirements of the secure image transfer.Experiment results prove that the encryption scheme is valid,and has high security simple and is easy to implement.Experiment simulation shows that the encryption algorithm has good effect of encryption.
