DNA Cryptography is one of the rapid emerging technology which works on concepts of DNA computing. A new technique for securing data was introduced using the biological structure of DNA called DNA Computing (aka molecular computing or biological computing) It was invented by Leonard Max Adleman in the year 1994, for solving the complex problems such as directed Hamilton path problem, NP-complete problem similar to The Travelling Salesman problem. The concept of using DNA computing in the fields of cryptography and steganography has been identified as a possible technology that may bring forward a new hope for unbreakable algorithms.”]
