This paper proposes a secure communication scheme for the master-slave framework using the concept of equivalent control for a class of chaotic SMIB power systems. For a given chaotic master system, a sliding mode controller introduced to the slave system can be constructed to synchronize the master system. Also the hidden message can be recovered directly by the concept of equivalent control. Theoretical analysis and numerical simulation verify the effectiveness of the proposed scheme.
