A Chaotic Clifford Attacker Map-based Image Encryption in Double Random Phase Encoding

Encryption is the most useful technique used for security of data during storage and transmission. A well-known encryption scheme called Double Random Phase encoding was introduced by Refregier Javidi. But due to its linear nature, this has been proven vulnerable against Known plaintext chosen attacks. Here in paper, we propose a chaotic map-based nonlinear that enhances DRPE images. Clifford attacker non-linear map four parameters two initial values. This highly sensitive these Therefore, values work as extra secret keys. MATLAB simulation shows proposed level at same time better immunity noise occlusion
