Hybrid Chaotic Encryption Algorithm for Securing DICOM Systems
Ge Jiao · International Journal of Performability Engineering · 2019
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 experiments and comparisons with existing algorithms to validate the characteristics of high security and low correlation of adjacent pixels of the proposed encryption algorithm.
