DNA computing is a new computational paradigm by harnessing the potential massive parallelism, high density information of bio-molecules and low power consumption, which brings potential challenges and opportunities to traditional cryptography. In this paper, on the basis of reviewing the principle of DNA computing and the development situation of DNA computing briefly, we analyze some schemes with secret key searching and introduce the application of DNA computing in encryption, steganography and authentication. In the paper we have DNA computing consist computation of DNA strands and its basic molecules like nucleotides. The aim of this manuscript is to illustrate the current state of the art of DNA computing achievements, especially of new approaches or methods contributing to solve either theoretical or application problems. Starting with the NP-problem that Adleman solved by means of wet DNA experiment in 1994, DNA becomes one of appropriate alternatives to overcome the silicon computer limitation. Today, many researchers all over the world concentrate on subjects either to improve available methods used in DNA computing or to suggest a new way to solve engineering or application problems with a DNA computing approach. This paper gives an overview of research achievements in DNA computing and touches on the achievements of improved methods employed in DNA computing as well as in solving application problems. At the middle of the paper we came to know actual mechanism of DNA computing along with DNA structure detail. At the end of discussion, we address several challenges that DNA computing faces in the society and also we focus on the different types of DNA computing applications.
