Abstract

Based on putting dynamic discrete-time hyperchaotic systems under forced two levels hierarchical structure, to derive new sufficient conditions of asymptotic stability, a new strategy of control is formulated for hyperchaos synchronization of two identical 3D Hénon maps. The designed state feedback controller ensures that the state variables of both controlled hyperchaotic slave system globally synchronize with the state variables of the hyperchaotic master system. Numerical simulations are carried out to assess the performance of the proposed contributions in the important field of encryption and decryption through hyperchaotic synchronization phenomenon.
