| 摘 要： | 确保数字图像信息的安全,是当前信息处理技术领域的难点和热点。混沌序列具有容易生成,对初始条件和混沌参数敏感等特点,近年来在图像加密领域得到了广泛的应用。提出了一种新的图像加密算法,利用两种混沌映射,分别对图像像素进行灰度置乱和位置置乱。实验和分析结果表明,此种算法具有密钥空间大、不易破解等特点,加密效果令人满意。

| Abstract: | Ensuring the safety of digital image information is a difficulty and hotspot in the domain of information processing technology nowadays.Chaotic sequence can be produced easily and is sensitive of the original conditions and parameters.In recent years,it is widely used in image encryption.In this paper,a new image encryption method is proposed,and the encryption process is disturbing color values of each image point and the array of original image based on two kinds of chaotic mapping.The results of experiments and analyses show that this encrypting method has a large space of keys and can't be decrypted easily,and the encryption effect is satisfactory. |
