More secure communication using chained chaotic oscillators
نویسندگان
چکیده
In this Letter, a strategy for more secure communication using chaotic signals is presented. In this approach, the transmitter is composed by a chain of chaotic oscillator where the input to the first oscillator is modulated by the information signal and the transmitted signal is the output of the last oscillator. The receiver is a linear asymptotic approximation to the inverse of the transmitter system and contains an integral feedback to cope with nonlinearities and parameter variations. The functioning of the information encoding/decoding system is illustrated with a cascade of colpitts and Chua’s circuits. 2001 Published by Elsevier Science B.V.

A Survey of Chaotic Secure Communication Systems
Secure communication using synchronization between chaotic systems(chaotic secure communication, for short) is a new concept of secure communication. The great potentials of this kind of “hardware key” secure communication systems had driven the progress of this field rapidly. Since 1992, chaotic secure communication had evolved four generations. In this paper, a detailed history of chaotic sec...

In recent years chaotic secure communication and chaos synchronization have received ever increasing attention. Unfortunately, despite the advantages of chaotic systems, Such as, noise-like correlation, easy hardware implementation, multitude of chaotic modes, flexible control of their dynamics, chaotic self-synchronization phenomena and potential communication confidence due to the very dynami...
متن کاملSecure Computer Communication Based on Chaotic Rössler Oscillators
We describe a communication scheme based on chaotic Rössler oscillators for transmission of secure messages via computers. The computers are synchronized through one of the channels via one of the variables of the Rössler system, while an information signal is transmitted through another channel by adding the message to another system variable. This scheme provides more stable communication bec...
متن کاملSpread Spectrum using Chaotic System
Chaotic signal helps in a secure communication, by generating wideband spectra of random sequences. Chaotic signal has the property of synchronization; data are transmitted from one location to another by mapping bit sequences to symbols, and symbols to sample functions of analog waveforms. The synchronization between two digital chaotic oscillators, serving as a transmitterreceiver scheme, is ...
متن کاملDigital Chaotic Synchronized Communication System
The experimental study of a secure chaotic synchronized communication system is presented. The synchronization between two digital chaotic oscillators, serving as a transmitter-receiver scheme, is studied. The oscillators exhibit rich chaotic behavior and are unidirectionally coupled, forming a master-slave topology. Both the input information signal and the transmitted chaotic signal are digit...
