ABSTRACT = {With the rapid development of medical informatization and the
popularization of digital imaging equipment, DICOM images contain the
personal privacy of patients, and there are security risks in the process of
storage and transmission, so it needs to be encrypted. In order to solve the
security problem of medical images on mobile devices, a safe and efficient
medical image encryption algorithm called ALCencryption is designed. The
algorithm first analyzes the medical image and distinguishes the color image
from the gray image. For gray images, the improved Arnold map is used to
scramble them according to the optimal number of iterations, and then the
diffusion is realized by the Logistic and Chebyshev map cross-diffusion algorithm. The color image is encrypted by cross-diffusion algorithm of double
chaotic map. Security and efficiency analysis show that the ALCencryption
algorithm has the characteristics of small neighboring pixels, large key space,
strong key sensitivity, high safety and short encryption time. It is suitable for
medical image encryption of mobile devices with high real-time requirements.},
