Abstract: In this paper, a novel secured transmission scheme implemented in Arduino-Uno boards is proposed. The transmission scheme is composed of two coupled discrete-time chaotic systems and two combined observers. In the first observer, some sufficient conditions on varying equal impulsive distance are established in order to guarantee the impulsive synchronisation method. In the second observer, an exact discrete-time observer is designed in order to reconstruct all states and the message information. Simulation results are presented to highlight the performances of the proposed method. One of the main contributions is to show that the proposed scheme, which is based on impulsive synchronisation of discrete-time chaotic systems is experimentally feasible with digital devices using the Arduino-Uno boards. The obtained experimental results validate the proposed approach.
