In this paper, we propose an asymmetric interference based encryption (IBE) using a modified error-reduction phase retrieval algorithm (mERPRA) in a structure of optical interference. Unlike previously proposed IBE schemes, the ciphertext in our scheme has less pixels than the original image. What is more important, a plaintext-dependent private key can be retrieved by using mERPRA with a fixed amplitude constraint, which makes this IBE scheme asymmetric. As we know, except for equal modulus decomposition-based encryption schemes, this is the first time that asymmetric IBE is presented. Consequentially, our proposed IBE scheme gains enhanced security due to its asymmetry. Simulation results are demonstrated to prove the validity of this scheme.

改进的减少错误相位检索算法基于光学干涉的非对称图像加密

在本文中，我们提出了一种在光干涉结构中使用改进的减少错误的相位检索算法（mERPRA）的基于非对称干涉的加密（IBE）。与先前提出的IBE方案不同，我们方案中的密文比原始图像具有更少的像素。更重要的是，可以通过使用具有固定幅度限制的mERPRA来检索与明文相关的私钥，这使该IBE方案变得不对称。众所周知，除了基于等模分解的加密方案之外，这是首次提出非对称IBE。因此，我们提出的IBE方案由于其不对称性而提高了安全性。仿真结果证明了该方案的有效性。
