Chaos Synchronization

Chaos synchronization is the central core of various message encryption methods which are developed based on the properties of chaotic systems. This chapter introduces the concept of chaos synchronization and its application in secure communication. Some standard approaches such as complete, lag, phase and generalized synchronization are defined first. Then application of control theory for synchronization of different chaotic systems is discussed. Some synchronization algorithms based on different control techniques are presented. It is shown that how the controlling methods can be modified in a synchronization framework to cope with parameter uncertainties and measurement noise. Several chaotic systems are simulated and synchronized to show the performance of the reported methods.
