摘要

本文研究了利用二值观测值识别有限脉冲响应（FIR）系统免受随机重放攻击的问题。对重放攻击进行了建模，研究了攻击策略对参数估计算法性能的影响。设计了一种即使在攻击过程中也保持一致的防御算法，并讨论了未知参数的可识别性问题。然后，给出了该算法的渐近正态性，并在此基础上导出了最优防御策略。通过仿真算例验证了该方法的合理性。

Identification of FIR Systems with binary-valued observations under replay attacks

We study the problem of identifying Finite Impulse Response (FIR) systems against random replay attacks with binary-valued observations in this paper. Replay attacks are modeled and the impact of attack strategies on the performance of parameter estimation algorithms is investigated. A defense algorithm that is consistent even during attacks is designed, and the problem of identifiability for the unknown parameters is discussed. Then, the asymptotic normality of this algorithm is given, and we derive the optimal defense strategy based on this. The proposed method’s rationality is verified by simulation example.

期刊介绍： Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field. After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience. Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
