Synchronization of Boolean networks with chaos-driving and its application in image cryptosystem

This paper proposes a Boolean network model with high dimensional chaos driving and investigates the synchronization of the chaos-driven Boolean network with a semi-tensor product. In order to protect the privacy and ensure the security of image transmission, the synchronization results are utilized in the image cryptosystem to achieve compression and encryption. First, the driving chaos system is coupled with multiple local systems and synchronized with the transmitted encrypted signals. Second, the Boolean network is driven and synchronized with derived chaos signals. Finally, images are encrypted and compressed with chaos-driven Boolean network signals in the transmitter, and then decrypted and recovered with synchronized chaos and Boolean network signals in the recipient. Because of the complexities of high dimensional chaos and Boolean network, the proposed cryptosystem has good security in the secure communication and image process. This paper proposes a Boolean network model with high dimensional chaos driving and studies the synchronization of the chaos driving Boolean network with a semi-tensor product. In addition, the synchronization results are utilized in the image cryptosystem to achieve compression and encryption. image
