In this paper we review a number of optical image encryption techniques proposed in the
literature inspired by the architecture of the classic optical Double Random Phase Encoding …

We demonstrate a method of chosen-plaintext attack on lensless double-random phase
encoding (L-DRPE) in the Fresnel domain. With this attack an opponent can access two …

Conventional double-random phase encoding is vulnerable to a chosen or known plaintext
attack owing to the linearity of the system. We introduce a technique to break down this …
