Abstract
Chaotic secure communication has many advantages than traditional communication for its broadband, noise like characteristics. Only after good features of the chaotic system being studied deeply, chaos-based secure communication can be applied. In the traditional secure communication based on Chaos Shift Keying (CSK), synchronization needs to be established between the transmitter and receiver of the system. While due to the extreme sensitivity of initial value of chaotic signal, it is very difficult to achieve synchronization so this method is difficult to be applied practically. Therefore to solve this problem, a new Differential Chaos Shift Keying (DCSK) system was proposed which chaos synchronization is not necessary. The new system was deeply studied and was compared with the Binary Phase Shift Keying (BPSK) modulation. Finally, a new application with DCSK in the image transmission was given.
