Summary:
This paper proposes the chaotic modulator with Volterra filter for cipher and secure communications. To achieve the practical chaotic modulator, the system supposes to use the digital communication line, such as the Internet, to maintain the parameter matching between the transmitter and receiver sides. Therefore, the higher coefficient sensitivity is requested when the parameters are mismatched. In particular, the information transmission is done in each packet that the length is 1500[byte] or less; therefore, when the parameter does not adjust, the chaotic system is necessary to shift to other orbits extremely quick. In this paper, the chaotic cipher with high coefficient sensitivity is proposed and the robustness is evaluated.
