Security Analysis of Discrete Nonlinear Systems With Injection Attacks Under Iterative Learning Schemes

In this study, the security problem of discrete nonlinear systems with injection attacks is discussed by designing two kinds of iterative learning schemes with the partial information and delay. The definitions of security and insecurity are presented and the injection attack is considered in a discrete nonlinear system. The contribution of this study is twofold: 1) two kinds of iterative learning schemes are designed to be with the partial information and delay due to limited bandwidth of networks and 2) two criteria are proposed to analyze the security and insecurity of a discrete nonlinear system with the two kinds of iterative learning schemes. Finally, numerical results are presented to illustrate the validity of the obtained criteria.
