Metamorphic Cryptography using 8-Way Dynamic DNA Sequencing & KIMLA Method

Abstract

In the digital world transfer of information can take place in secure way by encrypting the secret message and hiding encrypted message in to various multimedia such as text, image, audio & video. Cryptography along with steganography provides security by embedding the encrypted text message in such a way that any intruder is unaware about the message is embedded in it. Cipher text produced by encryption process that create confusion but the concept of steganography hiding doubtful characters of encrypted text message. So, it is well protected. This paper emphasizes on the encryption of secret text message and concealing the encrypted message in to gray scale image. To encrypt the secret text message 8-way dynamic DNA sequencing is used and for further security improved LSB (KIMLA) method has used an image for hiding the encrypted text message. The proposed approach provides better security & also efficient in term of payload capacity and robustness.
