A Hybrid Method with Lorenz attractor based Cryptography and LSB Steganography

Abstract

The rapid growth of internet made the human life easier. In internet the message transfer takes less time than conventional system. In this paper we propose an encryption technique which combines both cryptography and Steganography to protect information. . In this method we use chaos cryptography to encrypt the text where the initial parameters are taken as key and a new LSB Steganography technique to hide the cipher in image. Chaotic Systems are basically nonlinear and exhibiting an apparently random behavior for certain ranges of values of system parameters. Cryptography is protecting the privacy of the message where the Steganography is used for hide the information.
