Fuzzy and neural observer Based hyperchaotic oscillator for Secure communication

Abstract

Modern telecommunication networks especially the internet and newlinemobile networks have tremendously extended the limits and possibilities of newlinecommunication and information transmission Associated with this rapid newlinedevelopment there is a growing demand of cryptographic technique which newlinehas also spurred a great deal of research activities in this area Since 1990 newlinemany researchers have noticed the interesting relationship between chaos and newlinecryptography It has been observed that many properties of chaotic systems newlinehave their corresponding counterparts in traditional cryptosystems Actually, newlinethe cryptographic community had used discrete pseudo chaotic systems for a newlinelong time to generate cipher keys that has led to the application of chaos for newlinesecure communication newlineChaos is a universal and robust phenomenon in dynamic systems newlineThe chaos attracted wide attention after Lorenz published his research paper newlinein 1963 newline newline
