Combination between Steganography and Cryptography in Information Hiding by Using Same Key

Abstract

Steganography and cryptography are two popular ways of sending vital information in a secret way. One hides the existence of the message and the other distorts the message itself. In my algorithm I try combine between steganography and cryptography and use same key in both ways this mean the key that use in cryptography also use in steganography. We use transportation cipher to encrypt text by using specific key and same key that using in cryptography, again use in steganography and use LSB method in steganography with key in new technique. Keywords: Cryptography, Steganography, Information Hiding, LSB, Transposition Cipher
