Cryptanalysis of DRPE using complex S-Box based on linear canonical transform

During recent decades, double random phase encoding grasped more attention for researchers. To achieve nonlinearity, it had been done with S-Box. We exhibit this involvement that DRPE system is much vulnerable in the above methodology. Concatenating anything needs an imaginary value, wherein S-Box unsuccessful it. Used has reformed into various sizes. Due to scenario, values are replicating. So, complex employed and proposed size of similar input image. Numerical simulations such as performance analysis, histogram analysis 3D plot have performed out validate practicability trustworthiness traditional Moreover, order check cryptanalysis, other occlusion attack, noise chosen plaintext sensitivity also accomplished.
