الملخص EN

Digital images are now widely used in modern clinic diagnosis.

The diagnostic images with confidential information related to patients’ privacy are stored and transmitted via public networks.

Secured schemes to guarantee confidentiality of patients’ privacy are becoming more and more vital.

This paper proposes an adaptive medical image encryption algorithm based on improved chaotic mapping in order to overcome the defects of the existing chaotic image encryption algorithm.

First, the algorithm used Logisticsine chaos mapping to scramble the plain image.

Then, the scrambled image was divided into 2-by-2 sub blocks.

By using the hyper-chaotic system, the sub blocks were adaptively encrypted until all thesub block encryption was completed.

By analyzing the key space, the information entropy, the correlation coefficient and the plaintext sensitivity of the algorithm, experimental results show that the proposed algorithm overcomes the shortcoming of lack of diffusion in single direction encryption.

It could effectively resist all kinds of attacks and has better security and robustness.
