In digital communication systems, application of chaotic signals offers several advantages. One of the most important advantages is increased security which is due to their noise-like and broad spectrum characteristics. In order to find an efficient way for chaotic system synchronization and secure communications this paper combines chaotic masking and chaotic modulation encryptions. The proposed...
A number of methods have been proposed for synchronizing chaotic systems. The most widely used methods are continuous synchronization schemes. In a continuous synchronization scheme, chaotic systems are coupled to each other continuously such that synchronization errors converge to zero. In this paper, chaos synchronization in coupled discrete-time dynamical systems is presented. Simulation results...
In this paper, two chaos-based communication schemes to transmit encrypted information are presented. We use Generalized Hamiltonian forms approach to synchronize two unidirectionally coupled n-scrolls chaotic attractors. First, a scheme is set-up to transmit binary signals by applying chaotic switching technique. Both coupling signal and confidential message are send by only one transmission channel...
