摘    要:数字图像是重要的信息载体,数字图像加密是保护信息安全的重要方式.将Arnold变换应用到数字图像加密中,能有效地对图像进行置乱,使得未授权者无法获得有效信息.为提升加密的可靠性,通过将位置置乱和RGB颜色分量置乱相结合的方法对图像进行加密,经实验验证,算法加密效果良好.

关 键 词:信息安全  Arnold变换  图像置乱

Abstract:The image is an important information carrier and the image encryption is an important way to protect the security of information. Arnold transformation is applied to the image encryption and image scrambling,making unauthorized persons unable to obtain valid information. To further enhance the security of encryption, the position scrambling and color component scrambling combination can enhance the effect of the better encryption,which is proved by experiments.
Keywords:information security  arnold transformation  image scrambling
