Abstract
This paper presents a new technique for optical image encryption based
on chaotic Baker map and Double Random Phase Encoding (DRPE). This technique
is implemented in two layers to enhance the security level of the classical
DRPE. The first layer is a pre-processing layer, which is performed with the
chaotic Baker map on the original image. In the second layer, the classical
DRPE is utilized. Matlab simulation experiments show that the proposed technique
enhances the security level of the DRPE, and at the same time has a better
immunity to noise.
