Abstract
Research in multimedia security is devoted to medical image encryption. Cipher Block Chaining (CBC), Rotation Operations, and Random Permutations (RaPe) are proposed in this manuscript as a hybrid encryption algorithm for medical images. As a result, the RGB planes are scrambled in specified directions: horizontally, vertically, and diagonally. An exhaustive attack method is effectively protected against decryption utilizing this method since it completely erases the outline of encrypted medical images, blurs the RGB-level matrix distribution properties, and completely erases the outlines of encrypted medical images. The proposed system does not use a transform domain for deploying improved security. Various parameters can be used to test and analyze the medical image in this proposed approach to ensure its security and effectiveness. Utilizing the proposed method as an example of its effectiveness, pragmatic images are selected to demonstrate its practical application in medical image encryption.
