A Chaos-Based Image Encryption Scheme Using the Hamming Distance and DNA Sequence Operation

In this study, we introduced a new memristive chaotic system with the rich dynamic behavior, and then proposed chaotic-based image encryption scheme which is based on permutation–confusion–substitution structure. our scheme, Hamming distance used to design plain-related initial condition, generated sequences are assigned permutation, diffusion, substitution stages. permutation stage, an effect pixel confusion implemented through approach, double-ended select-swap scrambling strategy. diffusion DNA XOR operation followed by triploid mutation enhance strength of system. A number experiments extensive safety analysis have been carried out results fully justify that not only ensures desirable security but also has superior efficiency.
