Network security in video communications using chaotic systems

In this paper, we report implementation of encryption of the signal in networked environment using synchronized chaos. The science of chaos has successfully been explored and implemented in hardware for communication signals by Cuomo et all in 1993, although he (author himself) claimed that the mathematics behind the phenomenon was still obscure and not very clear. We are utilizing this unpredictable, random phenomenon called chaos to code our information by superimposing it on a chaotic signal. We applied this technique to different formats of data and results were 100% in the sense that decoded files were run without error. This testing scenario encourages use of chaos in information coding across networks. It is shown that, in this environment, the security breach may not be possible even if sender and receiver have compatible scramblers and descramblers, and the key is also known to the receiver.
