In a well-developed digital world, security plays a key role in transmission of images. An Optical architecture that transforms a primary image into Stationary white noise with the help of random phase mask is proposed. Unlike the traditional Double Random Phase encryption, the encoding is performed using Discrete Wavelet Transform and Fast Fourier Transform. Although it is simple, in practice it is vulnerable to various attacks. Chaotic shuffling is performed as preprocessing step of encryption and post processing step of decryption to enhance security and verified the idea in simulation. Extensive simulation studies have been performed and Discrete Wavelet Transform based Double Random Phase Encoding with Henon shuffling is found to be good.
