Paper Abstract

Optical encryption system is generally vulnerable to attacks based on phase retrieval algorithm. In this paper, an improved encryption scheme is proposed based on the coherent 4-f system and complementary masks. This pair of irregular shaped complementary masks are introduced to cut the ciphertext and regroup them. The stitched ciphertext has high immunity to ciphertext attacks based on phase retrieval algorithms. We have done numerically simulation to demonstrate the feasibility and validity of the proposed technique.
