Diversification Synchronization for Hyper Chaos of Cellular Neural Network and its Application Research
Zhang Xiao-hon · Journal of Chinese Computer Systems · 2014
CNN drive system is properly divided into linear and nonlinear based on the linear stability criterion of synchronous error system,and then a new dynamics system is constructed to be a response system in the case that all the eigenvalues of Jacobian matrix are negative. Due to the multiple values of eigenvalues of Jacobian matrix meeting the synchronization conditions,the response system corresponding to the same drive system is not only,therefore,we can construct a new dynamic system as diverse response system. The variation regularity for system error is verified by comparing the changes of different eigenvalues of Jacobian matrix and initial value,and the results of numerical simulation show that the synchronization method is diverse and effective. And the applications of signal hiding,text scrambling and image encryption prove that the synchronization method has feasibility.
