As one of secure communication means,chaotic communication systems has been well-developed during the past three decades.Technical papers,both for theoretical and practical investigations,have reached a huge amount in number.On the other hand,fractional chaos,as a parallel ongoing research topic,also attracts many researchers to investigate.As far as the IT field is concerned,the research on control systems by using fractional chaos known as FOC(fractional order control)has been a hot issue for quite a long time.As a comparison,interesting enough,up to now we have not found any research result related to Fractional Chaos Communi-cation(FCC)system,i.e.,a system based on fractional chaos.The motivation of the present article is to reveal the feasibility of realizing communication systems based upon FCC and their superiority over the conventional integer chaotic communication systems.Principles of FCC and its advantages over integer chaotic communication systems are also discussed.
