MODERN INFORMATION SAFETY AND ADVANCES IN APPLICATION RESEARCH OF CHAOS-BASED SECURITY COMMUNICATION

This article offers an overview of modern network information safety and chaos-based security communication. Some main basic concepts and the states of methodology development for contemporary networks safety and security communication are introduced at first. Three main techniques for chaos-based communication, including chaotic hiding, chaotic switching (shift keying)and chaotic modulating, are briefely discussed. In order to be convenience and comparison chaotic communication with conventional communication for practical applications, they are classified into three categories: analog-analog communication, analog-digit-analog Communication, digit-digit communication. Several possible candidate schems for current chaotic communication are described, reviewed and commented. These shemes have shown their feasible and are being in possible mature state of development for applications. To that end, the concerned issues of research and techniques development for future applications are addressed finally.
