Abstract:
Stabilization conditions are proposed in this paper leading to master and slave hyperchaotic systems synchronization. They are, essentially, based on the use of a new state feedback controller and of the aggregation techniques for stability study associated to the arrow form matrix for system description. Indeed, the synchronization property is considered as the main way guaranteeing the design of one high dimensional cryptosystem. The security of this proposed communication scheme is investigated through its key sensitivity study. Numerical simulation results point up the efficiency of these contributions as well as the success of image signal transmission for the considered cryptosystem, by means of two identical 4-D chaotic Lorenz Stenflo maps as transmitter and receiver keys.
