基于相位迭代算法的单像素双图像加密系统

Single-pixel dual image encryption system based on phase iteration algorithm

提出一种基于相位迭代算法的单像素双图像加密系统,实现了复振幅图像的加密解密。将复振幅图像的振幅和相位分别赋值为1幅图像,同时实现了2幅图像的加密解密。将这2幅图像加密成一系列单像素值,解密时需将照明图案作为密钥才可成功获取2幅图像的信息,抵抗了针对单像素加密系统的伪造攻击。最后,通过模拟仿真验证了加密系统的有效性和安全性。

A single-pixel dual image encryption system based on phase iteration algorithm is proposed to realize the encryption and decryption of complex-amplitude image.By assigning the amplitude and phase term of the complex-amplitude image to one image respectively,it can realize the encryption and decryption of two images at the same time.The two images are encrypted into a series of single-pixel values,and the illumination pattern is required as the key to successfully obtain information of the two images during decryption.In addition,the encryption system can resist forgery attack against encryption systems based on single-pixel imaging.Finally,numerical simulations verify the effectiveness and security of the encryption system.
