  Researchers in the field of DNA-based chaotic cryptography have recently
proposed a set of novel and efficient image encryption algorithms. In this
paper, we present a comprehensive summary of those techniques, which are
available in the literature. The discussion given in this paper is grouped into
three main areas. At first, we give a brief sketch of the backbone architecture
and the theoretical foundation of this field, based on which all the algorithms
were proposed. Next, we briefly discuss the set of image encryption algorithms
based on this architecture and categorized them as either encryption or
cryptanalyzing techniques. Finally, we present the different evaluation metrics
used to quantitatively measure the performance of such algorithms. We also
discuss the characteristic differences among these algorithms. We further
highlight the potential advances that are needed to improvise the present
state-of-the-art image encryption technique using DNA computing and chaos
theory. The primary objective of this survey is to provide researchers in the
field of DNA computing and chaos theory based image encryption a comprehensive
summary of the progress achieved so far and to facilitate them to identify a
few challenging future research areas.
