Emerging Techniques and Trends in DNA Cryptography

Shilpa George, Biji C.L., Achuthsankar S. Nair, Akhila Mathew


Abstract: This paper reviews recent research trends and methods in the field of DNA cryptography. An attempt is made to introduce biological background and the literature concerning the various DNA cryptography techniques mainly comes under Pseudo DNA cryptography and DNA steganography based on biomolecular operations. The paper explains some of the key algorithms in designing Pseudo DNA cryptographic scheme such as (i) DNA Insertion, (ii) DNA Substitution and (iii) DNA Complementary pair method. Later it comes with the approaches adapted in DNA steganography based on biomolecular operations like Polymerase chain reaction (PCR) based DNA steganography, DNA microdot technology, and DNA steganography using recombinant DNA technology. The paper further does a comparative analysis on these methods and argues the various challenges involved in biomolecular operations while designing the DNA ciphers.

Keywords: DNA cryptography, Pseudo DNA cryptography, DNA steganography, PCR, DNA Microdot, Recombinant DNA
