摘要： 利用截断面包师变换对图像进行加解密。首先介绍了截断面包师变换定义及其性质;然后采用截断Baker变换对图像进行加密运算,将加密后的图像和密钥分别从公共通道和密钥通道传输,解密算法是加密算法的逆过程。试验结果表明,截断面包师变换具有很好的统计特性,该算法能够得到令人满意的结果。

Abstract: The application of a truncated baker transformation to digital image is proposed. First, the definition and character of a truncated baker transformation are explained; Image encryption based on truncated baker transformation is done; Encrypted image and key are transmitted from public passage and secret passage independently. Decrypted algorithm is opposite to the encrypted algorithm. Examinations show that truncated baker transformation has the good statistical character and preliminary results are satisfactory.
