Nowadays, the increasing requirement for telemedicine services has raised more concerns in real-time medical image encryption. However, traditional block ciphers have been found poorly fit this requirement. Considering this, we propose an efficient cryptosystem for medical image encryption in the present study. Chaos-based permutation-diffusion architecture is adopted, whereas an improved image confusion strategy is developed based on the intrinsic feature of medical images. The improved confusion approach can bring about not only satisfactory permutation performance but also bit distribution balancing effect for medical images. Simulations and extensive security analyses indicate that the proposed cryptosystem provides an efficient approach for real-time secure medical image transmission and storage over public networks.
