Abstract

We propose a novel multiple image encryption based on fractional Fourier transform (FRT) and known-plaintext attack with modified Gerchberg-Saxton (G-S) phase retrieval algorithm. Multiple images to be encrypted are encoded into corresponding phase-only masks (POMs) using modified G-S algorithm. These POMs are multiplexed into a single POM, which may be referred to as a general key. The individual keys can be generated with the help of all the POMs. Now a random intensity image is encrypted using double phase encoding in which POM and random phase masks (RPM) are used as keys. For decryption, with the concept of known-plaintext attack using intensity image and RPM as keys, the POM is obtained. With this POM, the original images can be retrieved by using individual keys, and correct orders of FRT. We present simulation results with four different gray-scale images. Numerical simulation results support the proposed idea of the multiple image encryption.
