Summary:A 3D unified chaotic system and dynamic deoxyribonucleic acid i.e. DNA coding-based colour medical image encryption describe in this article. First, the pixels of the original image are circularly rotated horizontally, vertically, and diagonally at bit level. Next every associated two pixels are encoded into DNA bases using dynamic DNA coding. After that, positions of the DNA bases are altered in different directions, which makes extreme shuffling of DNA bases. Finally, the resultant DNA matrix is decoded using the dynamic DNA base decoding technique. Input values of every phase combine to form the decryption key. The runtime formation of decryption key makes the proposed algorithm more secure. The proposed algorithm is simulated, analysed, and tested with some standard evaluation parameters. The results of various tests are exceptionally encouraging and show powerful encryption execution on different types of images it also exhibits the strength of the proposed method against various kinds of cryptographic attacks.
