Decryption of communication by using super chaotic system with uncertain functions

Synchronization of chaotic system is used in secure communication because of the random type behavior of chaotic systems. But there is no absolute safe communication system. A new kind of decryption method is proposed in this paper by making use of the robustness of synchronization strategy. Also model with sender, receiver and unfriendly receiver is built and a decryption problem is transformed to be a synchronization problem with uncertainties.
