摘　　要：基于经典4f双随机相位图像加密技术,采用正弦多维有序相位编码光栅密钥进行图像加密及解密,给出一种新型图像加密方法。通过理论分析并进行了Matlab模拟,光学实验实现了有序密钥的图像加密效果佳,验证了多维有序替代无序随机的可行性,对解决随机相位密钥制作及解密时的不可控性有重要的意义,提高了光学图像加密的应用价值。Based on the classic 4f double random phase image encryption technology, using multi-dimensional sine orderly phase-encoding raster image encryption and decryption key, to give a new image encryption method. Theoretical analysis and simulation of Matlab, optical experiments to achieve the effect of image encryption key ordered Jia validated alternative multi-dimensional disordered random ordered the feasibility to solve the random phase decryption key production and non-controllable there is significant to improve the value of the optical image encryption.
