A Color Image Encryption Using One Quaternion-Valued Neural Network

Color image encryption via real-valued chaos system generally requires multiple real-value systems. To this end, this article presents a encryption algorithm for color image that requires only a quaternion-valued neural network system. First, an inertial memristor-based quaternion-valued neural network (IMQVNN) is proposed and the exponential synchronization criteria for the addressed systems are given. Then, an example and its simulation results are given to verify the rationality of the synchronization criteria. Based on the drive-response systems, a encryption algorithm for color image is therefore put forward. Finally, the effectiveness of the proposed cryptosystem is verified by the simulation results and security performance analysis.
