Abstract The paper investigates the event‐triggered security control of networked switched systems (NSSs) under denial‐of‐service (DoS) attacks through dual‐channel transmission. To actively defend against DoS attacks, a Stackelberg game is employed to characterize interaction between defender and attacker, with assuming role leader attacker as follower. Furthermore, simulated annealing algorithm utilized obtain equilibrium solution, from which packet loss rates dual channels are derived. In...

This paper investigates the stability of networked switched systems under DoS attacks by a Stackelberg game approach. Firstly, non-cooperative competition between attacker and controller is characterized as game. The delivery rate data packets gains compose strategy sets controller, respectively. Then, optimal obtained from corresponding equilibrium. Considering open-loop asynchronous switching cases caused attacks, sufficient conditions for exponential mean-square system are obtained....

The paper investigates the optimal energy scheduling in event-triggered redundant channel of cyber-physical systems (CPSs) to defend against Denial-of-Service (DoS) attacks. We consider an online DoS attack with pause and restart rules, a average restriction is employed for transmission when consecutive packet loss occurs. In addition, mechanism incorporated into determine activation instants. Aiming minimize expected estimation error covariance, corresponding level are proposed....

This article investigates the resilient control strategies of networked switched systems (NSSs) against denial-of-service (DoS) attacks and external disturbance. In network layer, both defender attacker allocate energy over multiple channels. Considering impact switching characteristic in physical layer on a dynamic regulating factor is proposed to adjust total defender. To optimize signal-to-interference-noise ratio consumption simultaneously at each player's side, multiobjective game...

In this article, the multiobjective optimization problem of networked switched systems under denial-of-service (DoS) attack is studied. DoS attacks launched by network layer attackers will affect performance in physical layer, so it necessary to deploy a defender deal with it. Taking account properties each subsystem and characteristics attacker group composed <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math...

This study investigates a denial-of-service (DoS) attack strategy against cyber-physical systems (CPS) under energy constraints. A DoS attacker with eavesdropping ability limited budget was considered. By scheduling the behavior based on historical results, aims to maximize state estimation error of CPS. novel pause and restart rules proposed, in which pauses for while restore after failed attempt. The rule described Markov chain modeling attacking period. transition matrix stationary...
