Abstract
This work utilizes a novel image encryption technique for block image encryption with the help of nonlinear 2D chaotic map and DNA sequences (NL2DCM-DNA). 2D chaotic map has generated the several key sequences for encryption, and DNA rules are applied to perform fast block encryption of image. Nonlinearity of 2D chaotic map and complexity of DNA sequences are used to perform highly secure image encryption. The experimental outputs illustrate the higher efficiency of NL2DCM-DNA in terms of security, attack resilience, entropy, histogram, running time and diffusion against some previous image encryption algorithms.
