Vulnerability of impulse attack-free four random phase mask cryptosystems to chosen-plaintext attack
Tuo Li, Yishi Shi · Journal of Optics · 2016
Abstract An attack-free four random phase mask 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 three-dimensional phase retrieval method. Our result, to the best of our knowledge, is the first work to show this security flaw in the attack-free four random phase mask cryptosystem. Meanwhile, a set of numerical simulations is provided to demonstrate the robustness of the presented method.
