Event-Triggered H_∞ Filtering for Networked Systems Under Hybrid Probability Deception Attacks

Abstract

In this paper, the deception attacks are the research object, which are widely concerned in cyber attacks, and the feasibility of H ∞ filtering for networked system based on event-triggered mechanism (ETM) is discussed. Firstly, in order to avoid waste of limited bandwidth, the ETM are introduced. At the same time, considering the impact of two types of different deception attacks, we introduce respectively two sets of random variables satisfying the Bernoulli distribution to depict the probability of the data transmitted by the network being subjected to deception attacks and the switching law of two types of deception attacks. Furthermore, a function model in accordance with the above situation is established. Then, by using Lyapunov-Krasovskii functional (LKF) and linear matrix inequalities (LMIs) techniques, the stability criterion of the established system model and the display expression of filter parameters are obtained. For the single integral terms in the derivative of LKF, we utilize Jensen's Inequality and reciprocally convex combination lemma (RCCL) to process them. Finally, the feasibility of the proposed method is verified by a simulation example. INDEX TERMS H ∞ filter design, event-triggered mechanism, deception attack, Lyapunov-Krasovskii functional.

Extended dissipative performance for a complex dynamical networks based on adaptive event‐triggered filter method subject to hybrid attacks

“…Therefore, based on Definition (2.4), the over all closed loop system ( 16) is mean-square asymptotically stable. Furthermore, it follows from (41) that…”

“…40 Simultaneously, the notion of hybrid cyber attacks, which combine several different cyber attack, was proposed. [41][42][43] Furthermore, many results have been presented to examine cyber-attacks when an event-triggered strategy is used to solve the stabilization problem of a networked control system. [42][43][44] So far as our author knows, no one has proposed an adaptive event-triggered filter method for complex dynamical networks that could be attacked by hybrid cyber attacks.…”

Adaptive event‐triggered pinning synchronization control for complex networks with random saturation subject to hybrid cyber‐attacks

“…With the advancement of networks and modern technology, cyber security has recently become more essential. As a result, 36 there has been a strong interest in investigating the impact of various cyber‐attacks on CNs. In particular, cyber‐attacks have been considered a leading challenge to network security, with the goal of disrupting control performance and degrading stability by destroying critical data transmitted across a network 37 .…”

PD-Like H∞ Control for Large-Scale Stochastic Nonlinear Systems Under Denial-of-Service Attacks

“…DoS attacks could randomly occur and can be modeled by the Bernoulli distribution process or Markov process with known statistical information [23]. Furthermore, for the case with unknown statistical information, the resulting DoS attacks are that CPSs (Cyber-Physical Systems) are, in essence, a class of switched systems consisting of a closed-loop subsystem in attack free and an open-loop subsystem in attack present [5], [34]. As such, the indicator of average dwell time can be employed to reflect the permitted duration [29].…”
