Abstract: The optimized distributed state estimation (SE) scheme is proposed for time-varying nonlinear complex networks (NCNs) subject to denial of service (DoS) attacks under the dynamic-data-encryption (DDE) scheme. The DDE scheme is adopted to ensure data privacy by dynamically updating a secret key during data transmission. In particular, the compensation-based measurement model against DoS attacks is established to mitigate the effect of DoS attacks. The main objective is to design a distributed SE scheme such that an optimized upper bound (UB) on the estimation error covariance (EEC) is guaranteed by appropriately designing the estimator gain (EG). Besides, a sufficient condition with respect to the uniform boundedness of SE error is presented. Finally, the viability of the proposed SE scheme is illustrated by a numerical simulation.
