A Survey on DNA Based Cryptography

Two level security needs the hiding of data into a cover medium that cover medium is also inserted into another cover media. Both cover media may be same or different depending upon features and applications. The paper study the DNA, operation on the DNA. Then the paper focus on DNA based security i.e. cryptography and Steganography by using DNA. This paper discusses DNA cryptography and the difference between the traditional and the DNA cryptography. This paper also brief the various work done in the field of the DNA cryptography.
