摘要：In this paper, we study the networked state estimation problem in the presence of a passive eavesdropper. Suppose that the eavesdropper is monitoring the data transmitted between sensor and estimator. To avoid the eavesdropper generating a stable state estimator, a new information coding scheme for state estimator is proposed. By preprocessing the information transmitted from sensor to estimator, under a condition that almost sure holds, the state estimation of eavesdropper will always diverge no matter how it is designed.
