Abstract

The correlation coefficient in this paper takes the coefficient as the evaluation index of decryption effect and analyzes the influence of different parameters on the addition and decryption effect of JTC optical images. The simulation results show that the correlation coefficient of JTC encryption system fluctuates with the center spacing. In order to achieve the best decryption effect, the best spacing between the original image and the key; JTC encryption system requires higher alignment of decryption key and encrypted image than longitudinal alignment; JTC encryption system can only when the encrypted image is close to one. These results provide a theoretical basis for the relevant experiments and reduce the difficulty of the experiment.
