摘要：
A new optical encryption system is presented in this paper. By replacing the random phase plates by random amplitude plates in the double random phase encoding system, a novel optical encryption system is formed. The Statistical characteristics of the autocorrelation function of the encoded image are investigated; we found that the original image had been changed into a complex-amplitude stationary white noise. As a result, this approach proved to be robustness against brute force attack. Computer simulations are performed and the results are consistent with theoretical analysis. Moreover, some properties of this method prior to double random phase encoding system are discussed.
