Khan Farhan Rafat · 2009
ldquoWe can scarcely imagine a time when there did not exist a necessity, or at least a desire, of transmitting information from one individual to another in such a manner as to elude general comprehension.rdquo The transfer or exchange of information from a source to its intended destination via some media is referred to as communication. Thanks to the recent advancements in Telecommunication sector and the mammoth growth of mobile industry which has made distant communication within reach of a common human being. Short message service (SMS) - a communication protocol for mobile phones and a newly evolved SMS-Texting language have emerged as the most widely used and accepted means of information exchange between mobile cell phones. SMS propagates over control channels and can carry up to 160 bytes of information. SMS-Texting is preferred way of communication when speed and urgency are a must without getting overheard. The ever increasing and never ending information flow on communication lines (being a subject of active and / or passive wire tapping) poses serious threats on the credibility of information as being genuine or not. Hence, there is a daring need for continuous evolution of new information hiding techniques and procedures to pace up with the drastic changes in communication and networking fields. This research paper aims at proposing an enhanced method for securely exchanging secret/classified information via SMS in context of SMS-Testing Language.
