Abstract: Cryptography is the process to secure sensitive information through the means of implementing security algorithms. Cipher text that is generated as output after algorithm implementation can be read only by authorized and authenticated persons after converting it into plain text. It is believed by security practitioner that cipher text is difficult to decrypt if reverse procedure plus key is unknown. Steganography on the other hand is the method of hiding sensitive information into carrier medium in such a fashion that its presence cannot be detected by unauthorized persons. . Metamorphic cryptography is the fusion of these techniques, cryptography and steganography. In paper presented, metamorphic cryptography concept is implemented. DNA (Deoxyribonucleic Acid) based cryptography is implemented to achieve cryptographic strength. Plaintext message which contain sensitive information is converted into its corresponding ASCII values. Obtained ASCII values is then changed into corresponding binary values. Apply binary index compression technique. Applying compression technique reduces data up to 50% which improves payload capacity. Output of the above steps is converted into sequences of DNA nucleotides. Concept of steganography is implemented with the help of LSB algorithm. Proposed metamorphic algorithm is secure as it utilizes the concept of DNA, have higher payload capacity as it uses binary index compression technique and simple to implement as LSB algorithm is used for hiding purposes.
