- Abstract
In this study, a secure filtering problem is investigated for a class of uncertain stochastic non‐linear systems. A novel multiple channel attack model is established to account for the missing measurements and random deception attacks, which are assumed to occur in the insecure networks. The concept of φ ‐level security is proposed to quantify the degree of security. With the techniques of stochastic analysis, sufficient conditions are derived to provide the filtering systems φ ‐level security. Moreover, secure filtering gains are characterised by the solution to a set of inequality constraints. Numerical simulations on a power grid system are exploited to illustrate the effectiveness of the proposed design methodology.
