DNA cryptography…life blood for new ERA computers

Internet is growing every day. But it became a great challenge to provide security to the data transferring through Internet. Though there are many security strategies developed, intruders are working with different methods to hack and modify the data. Now-a-days, DNA computing is one of the emerging research areas of Computer Science. The computational process speed is very high by using DNA computers when compared to traditional systems. When Adleman introduced the concept of calculating complex problems using DNA, most of the researchers concentrate on DNA computing to meet the challenges of solving the complex problems. Some of the researchers realised that the best information carrier is the DNA and also many of them are interested to develop different cryptographic algorithms to provide security using DNA which is going to be used in DNA Computer Systems. By using the bio Molecular technology, security keys generated by DES are extracted in short span. Keeping in view the importance of DNA, because of its inherent quality of parallelization and hugeness that stores enormous information, in this paper I would highlight the concepts of DNA computing and throw light on the various algorithms developed in the field of DNA cryptography.
