Abstract
Conference Title: 2016 2nd International Conference on Frontiers of Signal Processing (ICFSP) Conference Start Date: 2016, Oct. 15 Conference End Date: 2016, Oct. 17 Conference Location: Warsaw, Poland In this paper, a quantum image encryption based on scrambling-diffusion (SD) approach is proposed. The position information of the quantum image is scrambled by Arnold cat map followed by Fibonacci transformation to avoid iteration problem in each technique. Then, quantum gray-code is used to encrypt the gray-level information of the scrambled quantum image. Simulations and analyses indicate that the proposed quantum encryption approach achieves better performance than previous approaches.
