A Novel Image Encryption Technique Based on DNA Theory and Chaotic Maps

High inter- and intra-pixel redundancy and correlation among adjoining pixels of digital images make it crucial to secure during transmission over private channels. Here, we have exploited the chaotic and DNA theory to design a secure and robust image encryption approach. The characteristics including pseudo-randomness and ergodicity make chaotic systems to employ for image cryptography. Chaotic theory and DNA operations are employed in confusion and diffusion stages of image encryption, respectively. The control parameters of chaotic maps will be considered as a security key. Performance of the projected method is evaluated using entropy analysis, histogram analysis, and correlation matrices. The proficiency of the technique is also justified with prevailing techniques using various evaluation parameters.
