DNA crytography with encoding and decoding text message

Input text message is encoded and using DNA based encryption and decryption with xor. Finally Decoded and text message is extracted.

Securing data means taking protective digital privacy measures that are implemented to prevent unauthorized access to any kind of digital information’s shared over the communication network. In this paper, we have proposed a technique, how an individual user can protect their data’s which is shared over the communication network. One of the principal challenges of data sharing on the data communication network is its security. This is revolving around the fact that once there is connectivity between computers sharing some resources, the issue of data security becomes critical. Cryptography provides functionality for the encryption of data, and authentication of other users. The cryptographic methodologies are one of the popular ways of achieving data security by encrypting the messages to make them nonreadable. There are many cryptographic techniques available and it is an essential information security tool. It provides the four most basic benefits – Confidentiality, Authentication, Data Integrity and Non-repudiation. Nowadays the security of communication is a crucial issue over the internet and cryptography has come up as a saviour of this problem. In modern cryptography, it operates on binary bit sequences and it secures communication to possess the secret key only.
