Design and analysis of an image encryption technique using DNA computation and chaos function has been emphasized in the present paper. The plain image was scrambled using Henon map followed by the implementation of a DNA sequence addition operation over the scrambled image with the DNA sequence-based key generated by the Logistic map. Thereafter, the generated sequence was subjected to exclusive-or operation with partial key and modulo of sum of all the pixel values. The experimental and safety analysis highlighted that the proposed encryption technique was not only invertible and computationally efficient, but also had a large key space, was extremely sensitive to secret key credentials, had a high NPCR value and a low correlation coefficient, rendering the system efficient and secure against brute-force, statistical and differential attack.
