A Chaotic Secure Communication Scheme Based on Duffing Oscillators and Frequency Estimation
This work presents a new technique to securely transmit and retrieve a message signal via chaotic systems. In our system, a two-valued message signal modulates the frequency of a Duffing oscillator sinusoidal term. An observer is used in the receiver side to retrieve the sinusoidal signal that contains the message and a novel frequency estimator is then used to reproduce an approximated estimat...
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 کاملMore secure communication using chained chaotic oscillators
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 transmitt...
متن کاملDigital Communication Using a Novel Combination of Chaotic Shift Keying and Duffing Oscillators
In this paper, an improved technique for constructing Chaotic Shift Keying (CSK) for transmitting digital signals is introduced. In contrast to the classical methods where only two chaotic attractors, representing logic 0 and logic 1 are used to build CSK, the proposed system allows the chaotic transmitted signal to alternate among four different chaotic attractors. In addition, the transmitter...
متن کاملA Secure Chaos-Based Communication Scheme in Multipath Fading Channels Using Particle Filtering
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...
