title: Security risk of diffractive-imaging-based optical cryptosystem.
abstract: The well-known diffractive-imaging-based optical cryptosystem is breached in the paper. The decryption key of the system can be easily accessed by the opponent by using a new type of powerful phase retrieval method. Our result, to our best knowledge, is the first work to show the security risk of the diffractive-image cryptosystem. Meanwhile, we provide a set of numerical simulations to demonstrate the feasibility and robustness of the presented method.
