STEGANOGRAPHY IN NETWORK PROTOCOLS - INTRODUCTION

Steganography refers to the do by of writing isolated messages in such a personal manner that no integrity \napart from the mean recipient knows of the population of the message. The massage is \ndesiphered utilize a conceal key cognise only to the sender and the intended reciever. \nSteganograpgy is potential through the existiance of screen take.

With the design mode of internet \nincolving communication- radio link and colloboration which has led to exculpated system \nenviornment and internationally redundent specifications, Internet provides fatty gorunds for \nploriferation of steganograpgy (Kundur & Ashan, 2002). \n1. PREVIOUS educate :OVERT conduct IN internet PROTOCOLS \n Some of the earlier work on black channels in meshwork protocols was carried out by Girling \nwho heightened on Local battlefield Networks (local area network). He identify there are obvious implicit channels in \nthe LAN surroundings and introduce the ideal of wiretapper who monitors the activities of a \nspecific sender on the LAN. The covert communicators are the transmitter and the \nwiretapper (Girling, 1987). As an extension to Girlings work, focus on LAN protocols can be \nnoted in Wolfs work where he establishes that the encryption process, which is the fundamental
