Secure Communication Using Modified Fractional and Inverse Matrices Synchronization Methods

Synchronization and secure communication using some chaotic systems of fractional differential equations

Synchronization phenomenon has been studied intensively because of its application in many fields, and one of it is secure communication. There are many ways for synchronization, such as feedback method, adaptive techniques, time delay feedback approach, backstepping method, with nonlinear control [10]. We will prove here synchronization and anti-synchronization between two chaotic systems of d...

Secure Communication using Chaotic Synchronization of PLL

A technique of secure communication via chaotic synchronization is proposed. A suitable frequency modulated (FM) signal is used to drive two different phase locked loops (PLLs) in chaotic region to obtain two different chaotic signals. Out of these two signals one will be transmitted to the receiver PLL depending on the digital data. Receiver PLL synchronized with the transmitted chaotic signal...

Modified Chaotic Shift Keying using Indirect Coupled Chaotic Synchronization for Secure Digital Communication

In this paper, a modified chaotic shift keying method is proposed to transmit digital bits securely over a communication channel. The scheme is based upon encrypting the digital bits 0 and 1 into infinite levels by applying the keystream such that there is no recognisable pattern in the encoded transmitted signal. The encoded transmitting signal generated is shown to resist popular attack metho...

On chaos synchronization and secure communication.

Chaos synchronization, in particular isochronal synchronization of two chaotic trajectories to each other, may be used to build a means of secure communication over a public channel. In this paper, we give an overview of coupling schemes of Bernoulli units deduced from chaotic laser systems, different ways to transmit information by chaos synchronization and the advantage of bidirectional over ...
