State feedback-based secure image cryptosystem using hyperchaotic synchronization.

This paper deals with a new state feedback-based synchronization problem for coupled hyperchaotic systems. In the beginning, complete synchronization conditions of coupled chaotic systems, are provided. The active control law developed is based on the use of both aggregation techniques for error dynamics stability study and the arrow form matrix for systems description. After that, the proposed feedback-based synchronization between two identical hyperchaotic systems is successfully applied for transmitting an encoded image. To finish, numerical simulations are carried out to assess the performance and the efficiency of the proposed contributions in the important field of secure image encryption.
