A new approach for secure communication using constrained hyperchaotic systems

作者：

Highlights：

• A new constrained hyperchaotic system is presented.

• A secure communication scheme using the generated chaotic signals is proposed.

• The CRLS estimator for nonlinear systems is used for chaos synchronization.

• The CRLS estimator and the convergence of its nonlinear update phase are analyzed.

• Simulation results demonstrate the proposed secure scheme effectiveness.
