DNA Computing in Security Highlights

DNA computing is an innovative approach to extremely match the computation based on the pioneering work by Leonard M Adleman; he has laid the foundation for bio-molecular computing.This is also known as Molecular Computing. With the not-so-good results of the modern encryption algorithms, there is a need for a new concept for protect the data transmission. DNA computing in the field of cryptography has been recognized as a potential technology for unbreakable algorithms. This post provides more details about DNA computing in security.


DNA computing is a method of simulation of bio-molecular structures of DNA and then doing the computation using the molecular biology technological computation. It pioneers a new data structure and calculation method thus offering a new way for deciphering the NP- complete problem.

DNA computing provides parallelism which implies that if adequate DNA data is given, massive problems can be solved by raising a parallel search. The great memory density of bio-molecules fetches potential challenges to the conventional cryptography. DNA cryptography has the ability to realize many security technologies like steganography, encryption, authentication and signature by making use of DNA molecular information medium.

 More about DNA computing in Security

 One of the most promising applications of DNA computing excluding storage is security. Security for data transfer is becoming more and more crucial as the quantity of data being transferred on internet is increasing. DNA is stable for millions of years and is hence perfect for using it for security reasons. Steganography and Cryptography aid in deciphering and developing safe algorithms in order to provide security for data communication over the net.


The entire secret of DNA computing in security lies in the microdots which are used for concealing message. Microdot is nothing but a diminished image of type written page which is glued over a dot. The cryptographic method aids in DNA based data security by making use of ‘DNA cryptography’ and ‘Pseudo cryptography’. The steganography method has two different techniques- simple steganography and DNA based doubly stereography.

Future of DNA Computing

The future of DNA computing in security is not clear; however, with endeavoring research in Bioinformatics field, the applications of molecular and DNA computing will be the obvious preference for secure data transfer using steganography and cryptography.

The Bottom Line

DNA computing in security keeps up the promise of protected connection between the computer and living system. The information holding capability of the DNA molecules are undoubtedly a ground-breaking technology and a great accomplishment of modern genetics theory in the field of Bioinformatics.

The correct architectural feature of DNA molecules can greatly assist to create a revolution in the field of DNA computing for security. DNA computing is expected to be the next corner stone in the world of data security.
