The development of cryptography and cryptographic analysis are regarded as active research trends, as security is one of the major concerns of civilized society. The present paper focuses on DNA cryptography. It is known for the discovery of Deoxyribonucleic Acid's computing capability (DNA). The work has been carried out with the help of several molecular manipulation techniques. In the present work, DNA is used as the computational tool in DNA cryptography. This topic is becoming quite promising since DNA has a very large capacity for storing information. It is an emerging area which is going to explore lots of effort for further implementation. This article outlines the paths that need to be further explored in the area of DNA cryptography by examining all the possibilities and cutting-edge technology of recent trends.
