Arduino-based chaotic secure communication system using multi-directional multi-scroll chaotic oscillators

The experimental realization of a chaotic secure communication system is introduced herein taking advantage of Arduino's open source integrated development environment along with its preset functions that reduce development time and complexity. The system uses multi-directional multi-scroll chaotic oscillators that are based on piecewise-linear functions. Experimental results are given for chaos generators in 1-direction (1-D), 2-D and 3-D of up to 20, and scrolls, respectively. Using two chaos generators, a chaotic secure communication system is implemented in a master-slave topology by applying generalized Hamiltonian forms and observer approach. Finally, we detail experimental results for the synchronization of and scroll attractors, which are used for transmitting a monochromatic image through the Arduino-based chaotic secure communication system.
