An improved data security using DNA sequencing

Data security is one of the most significant concerned areas of communications and data transmission. The concept of making secure data is to transform a plain message that is understandable by everyone into a human unreadable format or difficult to make out by encoding message using some cryptographic algorithms. Now a day, security is one of the most significant and fundamental issues of data transmission, researchers are working on the evolvement of new cryptographic algorithms. Cryptography is the process of providing security in data while transmitting over public networks by encrypting the original data or message. Data security is concerned with the areas of communication and data transmission. An efficient direction of achieving data security can be termed as DNA based Cryptography. The encryption and decryption process proposed in this paper will use the DNA sequencing string of the DNA strands. We have proposed here how the DNA sequencing can be utilized in cryptographic algorithms and how the message can be made more secure and reliable for transmitting effectively through networks. The algorithm we have proposed here is a new algorithm which has three keys for encrypting the message along with a new method of key generation and key sharing for better security aspects. The cipher text generated by the algorithm is looks similar with the bio-logical structure of the DNA strands. Unnecessary bits are padded with the cipher text in order to make it more complex to the intruders. The encryption algorithm is designed here by using the property of DNA sequencing.
