Tri Layer Model for Color Image Ciphering Through DNA Assisted 2D Chaos
In this modern digital world, there are many advancements that are made in the fields of networking. These days many multimedia messages, in the form of images are shared online for communicating with each other. The images thus send are vulnerable to attacks which are both internal (noise attack etc.) and external (hackers). An algorithm for securing these multimedia messages have been proposed here. The key employed in the proposed scheme is made from three different 2D chaotic maps. A colour image is split into RGB planes, it undergoes a 3-level confusion-double diffusion using Deoxyribo Nucleic Acid (DNA). A novel methodology has been approached to substantiate it over the currently existing encryption standards. The ability to withstand brute force attack, noise attack, chosen plain text attack of the method are to be tested.
