Abstract This paper addresses the problem of network security for distributed filtering when subject to malicious cyber attacks. First, based on the Dempster–Shafer (D‐S) theory a protector for each sensor is proposed, that can decide whether to use data sent by neighboring sensors. Furthermore, a distributed estimator is proposed for the nonlinear system with the designed detector. Besides, a sufficient condition is presented for the stability of the estimator equipped with the designed protector when under cyber attacks. Finally, several numerical examples are presented to verify the proposed protection strategy's efficacy.
