Özet

Communication networks, play a major role in keeping us connected and sharing the details of our lives with each other. The main driver of multimedia data transmission is to enhance security protection of this multimedia data (speech, image and video). In this paper we addresses the synchronization problem of the masterslave type via a static error feedback. Sufficient conditions expressed by means of linear matrix inequalities (LMI) for the synchronization of fractional-order hyperchaotic systems with a known time delay between them is presented. The delay-dependent criterion is given based upon a Lyapunov function. We take the fractional-order hyperchaotic Liu system as an illustrative example to demonstrate the effectiveness of the proposed synchronization scheme. Moreover, as an application an images cryptosystem is presented. We considered two scenarios corresponding to the transmission channel, under occlusion attack and under noisse addition respectively. Results for the studied scenarios are presented and compared. The extensive simulation results prove that proposed cryptosystem has clear advantage over other proposed in the litterature.
