The DICOM system contains patients' personal privacy and may present a risk of information leakage in telemedicine diagnostics. In order to solve the security problem of the DICOM system, we propose a medical image encryption method based on the cross-diffusion of the logistic map and the Chebyshev map. We first parse the DICOM image and read the data elements, and then we use the logistic map and the Chebyshev map to generate a key. Then, we cross-use these two sequences for further image encryption diffusion. Finally, we conduct in-depth expe...
