摘要：Background: The growth in the field of communication has enabled the people at miles apart to communicate easily. Once the online sharing of information is made possible. It is necessary to ensure about the security of the information that is shared. Materials and Methods: In this study, three levels of encryption process has been carried out. Quantum Key Distribution(QKD) with bit XOR forms the first level of encryption. Flipping and swapping of the ciphered block images were done using quantum walk principle forms the second and the third level of encryption. Results and Discussion: To prove the robustness of the proposed scheme, image encryption metrices like horizontal, vertical, diagonal correlations, No. of Pixel Change Rate (NPCR), Unified Average Changing Intensity(UACI) were estimated and compared with the available literature. Conclusion: The QKD and quantum walks forms the basic level of image encryption and offers NPCR 99.68 and UACI of 30.50. Flipping, swapping and bit XOR of the ciphered block images were done. To verify the robustness of the proposed method and the values are found to be better.
