Secure Colour Image Encryption Based on Dynamic DNA Coding and Different Chaotic Maps

In recent years several chaos-based encryptions have been developed due to its extraordinary property, but its debris is an inexorable discrepancy for developing efficiency and security. In this paper, a new colour image encryption and decryption scheme with different dimensional chaos functions has been used. Onedimensional logistic map, two-dimensional Sine-Henon alteration map, and three-dimensional Lorenz chaotic systems have been applied in different stages of the encryption model. Moreover, to protect from different types of attacks, dynamic DNA sequences with its reversible operations have been applied. Different experimental outcomes exhibit the effectiveness and efficiency of the proposed method. It is also proved that the proposed method can combat statistical attack, differential attack and exhaustive attack.
