Abstract Synchronization of generalized Hénon hyperchaotic system is studied. A new control scheme to synchronize generalized Hénon hyperchaotic system based on the exact linearization and invariant mani- fold theory is proposed. The merit is that the controller is contrasted only by the system output and its delay values. Therefore, it avoids the non-measurability of other state variables and has more advantages to the application in practical engineering. Based on that, a scheme for the synchronized systems to secure communication is presented. The results of the computer simulation show the validity of the proposed method and the feasibility of the communicating scheme.
