Paper Abstract

We consider a Double Random Phase Encoding (DRPE) Encryption/Decryption system in which the image encryption/decryption process is performed numerically. In this paper we present a key-space analysis of the (DRPE) algorithm which is used to encrypt two dimensional (2-D) images. We map the assiocated error for every phase-key in the key-space of a particular system to get a visual representation of the spread of phase-keys for the system and so assess its security from a key-space perspective.
