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 it’s security from a key-space perspective.
