Csk Based Secret Communication

The notion of non-linear dynamics has become an energetic and fashionable field of work that is having a thoughtful effect on a wide variety of topics in present day technology. One such evolution of non-linear dynamics is the chaos theory. It is not about disorder, rather is about very complicated systems of order. However, the point of interest lies in bridging the gap between random nature of chaotic signals and the demanding needs of Information safety. Hence, Safety via ambiguity is employed to ensure correct and complete transaction of data. A good solution to bring ambiguity is to materialize the message signal as unsystematic information. Consequently, Safety via ambiguity is resolved by a technique called Chaos shift keying. The technique is all about replacing one’s and zero’s of the message signal by the chaotic signals. The simulated results and future scope are discussed. It has been found that CSK modulated waveform looks exactly like a wideband noise. Hence even if a third party tries to hack the system, nobody can be able to judge any significant information is present or not.
