The design of chaos-based secure communication via synchronized modified Chua's systems is investigated in this paper. A continuous control law is proposed to ensure synchronization of the master and slave modified Chua's systems by using the variable structure control technique. Particularly, the concept of extended systems is introduced such that a continuous control input is obtained to avoid chattering phenomenon. Then, it becomes possible to ensure that the message signal embedded in the transmitter can be recovered in the receiver.
