摘要：Lately chaotic secure communication is attracting large interest due to the simplicity in design over other encryption methods such as conventional methods. In this paper, two message signal encryption models are designed based on Qi hyper-chaotic system and their efficiency and effectiveness are evaluated by calculating the Bit Error Rate (BER). The robustness of the two models is also estimated using power spectrum analysis and low pass filter method. MATLAB\SIMULINK is used to verify the proposed models.
