DNA cryptography is used to encrypt message for secure communication on a network. It is a information carrier for transferring message from sender to receiver. For secure communication, it is not only to encrypt message but also necessary to hide encrypted message. DNA cryptography is also used for hiding the data, Hidden message is known by only sender and receiver. DNA computing is used to solve problems in cryptography, cryptanalysis and steganography. DNA sequences based data encryption seems to be a promising strategy for fulfilling the current information security needs. This paper focus on the comparative study of some existing works on DNA Cryptography. Message transmission is a process to transmit encrypted data through secure communication channel using DNA cryptography. Text message is encoded in DNA sequence. Message transmission process reduces the time complexity of transferring encrypted message. Bio molecular and one-time- pad technologies is used for secure message encryption.
