Discrete-time synchronization of chaotic systems for secure communication [PDF]
This paper deals with the problem of designing an exact nonlinear reconstructor for discrete-time chaotic encrypted messages. More precisely, we investigate the problem of designing a discrete-time dead-beat observer for nonlinear systems with unknown ...

Observer-based secure communication using indirect coupled synchronization [PDF]
In this paper, an observer-based secure communication system composed of four chaotic oscillators is proposed. Observer based synchronization is achieved between two of these oscillators and employed as a transmitter and a receiver.

Symbolic dynamics and chaotic synchronization [PDF]
Chaotic communications schemes based on synchronization aim to provide security over the conventional communication schemes. Symbolic dynamics based on synchronization methods has provided high quality synchronization (5). Symbolic dynamics is a rigorous way to investigate chaotic behavior with finite precision and can be used combined with information

Combination Synchronization of Three Different Fractional-Order Delayed Chaotic Systems
Time delay is a frequently encountered phenomenon in some practical engineering systems and introducing time delay into a system can enrich its dynamic characteristics. There has been a plenty of interesting results on fractional-order chaotic systems or

The importance of choosing attractors for optimizing chaotic communications [PDF]
In this brief, we consider methods to improve the performance of chaotic communication schemes. We study a system using a receiver which explicitly includes the presence of noise in the channel.
