DNA Cryptography

As some of the modern cryptography algorithms (such as DES, and more recently,MD5) are broken, the new directions of information security are being sought to protect the data. The concept of using DNA computing in the fields of cryptography and steganography is a possible technology that may bring forward a new hope for powerful, or even unbreakable, algorithms. It is Adleman, with his pioneering work [Adleman, 1994]; set the stage for the new field of bio-computing research. His main idea was to use actual chemistry to solve problems that are either unsolvable by conventional computers, or require an enormous amount of computation. By the use of DNA computing, the Data Encryption Standard (DES) cryptographic protocol can be broken [Boneh, et. al,1995]. The one-time pad cryptography with DNA strands, and the research on DNA steganography (hiding messages in DNA), are shown in [Gehani, et. al, 2000].
