Chapter 13

Secure estimation subject to cyber stochastic attacks

Abstract

Cyber-physical systems (CPSs) are the integrations of control, communication, and computation that together acquire the desired performance of physical processes. Security threats have a high possibility of affecting CPSs and can be affected by several cyber attacks without providing any indication of failure.

One important problem, especially in power systems, is the estimation problem of systems under cyber attack. In the first section, a secure estimator for discrete-time delayed nonlinear systems considering both DoS and deception attacks will be presented. The occurrences of the DoS and deception attacks will be considered as Bernoulli distributed white sequences with ...
