提出了一种基于对易和反对易规则的图像加密算法。根据对易和反对易规则,将一个图像在水平方向和垂直方向上的两个一维傅里叶变换或分数傅里叶变换叠加在一起,可以加密成两个图像。用对易规则获得的图像可视为加密图像,用反对易规则获得的图像可视为解密密钥。数值结果证明了该方法的有效性,并证明了分数阶作为额外密钥对安全性的增强。设计了一个光学装置来实现所提出的方案。
A novel image encryption algorithm based on the commutation and anti-commutation rules is proposed. An image can be encrypted into two images by superposing its two one-dimensional Fourier transforms or fractional Fourier transforms in horizontal and vertical directions according to the commutation and anti-commutation rules. The image gained with commutation rule can be regarded as the encrypted image and the other gained with anti-commutation rule as the decryption key. Numerical results have demonstrated its effectiveness and shown the enhancement in security with the fractional orders as the extra keys. An optical setup is also designed to implement the proposed scheme.
