Secure Communication Scheme based on A New Hyperchaotic System

摘要

This study introduces a new continuous time differential system,which contains ten terms with three quadratic nonlinearities.The new system can demonstrate hyperchaotic,chaotic,quasi-periodic,and periodic behaviors for its different parameter values.All theoretical and numerical analysis are investigated to confirm the complex hyperchaotic behavior of our proposed model using many tools that include Kaplan-Yorke dimension,equilibrium points stability,bifurcation diagrams,and Lyapunov exponents.By means of Multisim software,the authors also designed an electronic circuit to confirm our proposed systems’physical feasibility.MATLAB and Multisim simulation results excellently agree with each other,which validate the feasibility of our new ten terms hyperchaotic system and make it very desirable to use in different domains especially in chaotic-based communication.Furthermore,by employing the drive response synchronisation,we developed a secure communication strategy for the proposed system.Findings from the proposed scheme show that the proposed approach was successful in completing the encryption and decryption procedure.
