Abstract

Abstract Pathological image encryption can help protect medical privacy. The paper proposes a color pathological image encryption scheme where three S-boxes are utilized to encrypt the red, green and blue components alternately. The S-boxes generated by complex chaotic system are changed dynamically, for the initial values and parameter are dependent on both the plain image and the environmental noise. The S-box switching sequence for each color component is also generated by complex chaotic system. Some effective measures have been taken to speed up the processes of encryption and decryption. Simulation result demonstrates that the scheme is suitable for color pathological image encryption.
