Abstract
Cryptography is a science of encoding a secret message in a manner so that any other person other than the receiver and the sender cannot be able to decode it, whereas the steganography is the science of concealing the information in any other cover media so that an attacker cannot recognize the presence of the secret message inside the cover media. This paper proposes a method using combined technologies of cryptography and steganography by following the concept of genetic engineering based on the DNA. This approach will enhance the message security, which is the main concern in today’s world for message transmission. In this proposed algorithm, a long and strong 256-bit key is used for encryption with a strong new method of encryption, generation of DNA sequence, and a new method to conceal the encrypted DNA sequence to a cover image, which provides better security in the message against the intruders attack.
