论文摘要
对于地理分离的网络物理系统，远程监控或控制位点的状态估计对于确保系统的稳定性和可靠性很重要。通常出于安全或商业原因，有必要确保流程状态和控制信息的机密性。当前感兴趣的主题是机密状态信息的私人传输。许多编码方案的传输依赖于承认，这可能容易受到对手的干扰。我们考虑一个隐秘的入侵者，有选择地阻止致谢，允许窃听者获得可靠的州估计，以击败编码方案。我们利用贝叶斯最快的更改检测技术来快速在线检测远程发射器和接收器的入侵者的存在。
For geographically separated cyber-physical systems, state estimation at a remote monitoring or control site is important to ensure stability and reliability of the system. Often for safety or commercial reasons it is necessary to ensure confidentiality of the process state and control information. A current topic of interest is the private transmission of confidential state information. Many transmission encoding schemes rely on acknowledgments, which may be susceptible to interference from an adversary. We consider a stealthy intruder that selectively blocks acknowledgments allowing an eavesdropper to obtain a reliable state estimate defeating an encoding scheme. We utilize Bayesian Quickest Change Detection techniques to quickly detect online the presence of an intruder at both the remote transmitter and receiver.
