确保基于监控和数据采集的系统的安全性是一个重大挑战。本文的目标是开发基于模型的技术，能够检测对控制系统传感器的完整性攻击。本文分析了完整性攻击对控制系统的影响，并提出了能够揭露此类攻击的对策。本文的主要贡献在于列举了重放攻击可行的条件，并提出了通过放弃控制性能来优化检测概率的对策。文中给出了方法，并通过多组仿真验证了理论结果。
Ensuring security of systems based on supervisory control and data acquisition is a major challenge. The goal of this paper is to develop the model-based techniques capable of detecting integrity attacks on the sensors of a control system. In this paper, the effect of integrity attacks on the control systems is analyzed and countermeasures capable of exposing such attacks are proposed. The main contributions of this paper, beyond the novelty of the problem formulation, lies in enumerating the conditions of the feasibility of the replay attack, and suggesting countermeasures that optimize the probability of detection by conceding control performance. The methodologies are shown and the theoretical results are validated using several sets of simulations.
