A speech scrambling is an important method to enhance the information protection in wireless communication systems. The main goal to achieve the security and high immunity against malicious eavesdroppers and attacks. In this paper an efficient Simulink model, speech scrambling based chaotic maps, random chaotic maps have been more success by using for encryption of data such as voice, video and text, because it possesses high sensitive to initial values and model external parameters. In addition, the paper1 use double chaotic maps Logistic and Henon to generate encrypted secret keys. A Simulink of the proposed techniques has been executed by using MATLAB SIMULINK (R2018a). A performance of this model is calculated and measured, the excellent results.
