Identification of Wiener systems with binary-valued outputs subject to sequence-type DoS attacks: optimal attack strategy

With the widespread application of Cyber-Physical Systems in critical infrastructure, security concerns have become increasingly prominent, especially regarding the degradation of system identification and control performance under Denial-of-Service (DoS) attacks. This paper investigates the parameter identification problem of Wiener systems with binary-valued outputs under sequence-type DoS attacks. Under the combined influence of binary measurements and DoS attacks, the strong convergence and asymptotic normality of the proposed identification algorithm are analysed. The optimal attack strategy is formulated as a constrained optimisation problem, using the trace of the error covariance matrix as the optimisation criterion, and solution methods for different scenarios are provided. Finally, numerical simulations are conducted to validate the effectiveness of the proposed conclusions and methods.
