Synchronization of Chua’s circuits with multi-scroll attractors: Application to communication

In this paper, the synchronization problem of coupled Chua’s circuits generator of n-scroll chaotic attractors in master–slave configuration is numerically studied. In particular, we consider a modified Chua’s circuit generator of 5-scroll chaotic attractors by using Hamiltonian systems and state observer approach. A potential application to transmit encrypted audio and image information is also given.
