More secured text transmission with dual phase message morphing Algorithm

Abstract

In this global village, where with the advancements in the field of communications, ensuring security to the data being transmitted has become very vital. These safety and security issues contributed to the outgrowth of secret communication. While encryption simply encodes the data making it difficult for the layman to understand, Steganography deals with hiding data within another data making them unaware of it. Both concepts ensure data security but in different forms. These two approaches when unified provide much better security to the data than that provided by either of encryption or Steganography. This paper proposes such a new unified approach for Secured Text Transmission using Dual Phase Message Morphing (DPMMA) algorithm, which encrypts and conceals data in two consecutive stages to provide better security to the data. This algorithm is a simple unified approach of encryption and Steganography which employs two newly proposed techniques for encryption and Steganography to provide better security for the data. As the name suggests it works in two consecutive phases. In the first phase encryption is performed and in the second phase the encrypted message is concealed within another text. The result of these two phases produces a morphed text which does not resemble the original message. © 2012 Springer-Verlag GmbH Berlin Heidelberg.
