Abstract: Chaotic systems have several significant features favorable to secure communication, such as aperiodicity (useful for one-time pad cipher); sensitivity to initial conditions and parameters (useful for effective bit confusion and diffusion); and random behaviors (useful for producing output signals with satisfactory statistics). Thus, chaotic systems and their application in secure communication have received increasing attention. Up to now, four main secure communication schemes based on chaos synchronization have been investigated, such as chaos masking, chaos shifting key, chaos modulation, and chaos spread spectrum. In fact, chaos synchronization is one of the key technologies in the chaotic secure communication for its practical use. So I will focus on the chaos synchronization and chaos secure communication schemes in my talk.
