state estimation for nonlinear networked systems subject to deception attacks. Because of the constrained networked communication resources, an event-triggered communication scheme is implemented to deal with this problem. The communication network is assumed to be subject to stochastic deception attacks which aim to replace the normal transmitted data. We firstly establish the estimation error system under the event-triggered communication scheme and the deception attacks. Based on the model, the exponential stability criteria are derived. Moreover, the event-triggering parameter and the state estimator gain are co-designed. Finally, the obtained results are verified by a numerical example.
