Multiswitching Synchronization of Non-Identical Hyperchaotic Lorenz and Chen Systems

In this paper, synchronization of four-dimensional hyperchaotic Lorenz system, (drive system) with the Chens system (response system) are investigated based on backstep- ping technique. Unlike the well-known i = j, multiswitching of the indices was employed in the usual master-slave synchronization scheme. We provided varieties of non-identical indices, that is, i = j of the driver system. In this high dimension, more switching options for construct- ing the error space vector due to the large number of variables are available, and by implication providing variety of synchronization directions between variables of the master and the slave systems, which could be used in securing electronic information and communication.
