In recent decades, image encryption has been a popular and important field of research. The techniques have studied thoroughly to ensure the safety digital images on transmission through networks. A large range algorithms for chaotic-based cryptographic systems suggested submitted enhance efficiency methods. chaotic map is one technique guarantee security. benefits include fact that it simple i...

in this paper, under the existence of system uncertainties, external disturbances, and input nonlinearity, global finite time synchronization between two identical attractors which belong to a class of second-order chaotic nonlinear gyros are achieved by considering a method of continuous smooth second-order sliding mode control (hoamsc). it is proved that the proposed controller is robust to m...
