论文摘要
在网络物理系统（CPS）中，基于通信数据的推理具有至关重要的意义，因为它可用于操纵或损害对手的控制操作。由于控制系统越来越多地分布在较大的地理区域，因此需要有效的数据进行安全传输。最近提出的基于失真的安全性是CPS中安全传输的一个候选人，不仅适合这些应用程序，而且在共享密钥上的先前要求方面也很节俭。在本文中，我们提出了基于失真的指标来保护CPS通信，并表明只有几个前共享的密钥将对手混淆。特别是，我们将表明线性动力系统可以以防止窃听者准确地学习状态的方式传达其状态。
In Cyber-Physical Systems (CPS), inference based on communicated data is of critical significance as it can be used to manipulate or damage the control operations by adversaries. This calls for efficient mechanisms for secure transmission of data since control systems are becoming increasingly distributed over larger geographical areas. Distortion based security, recently proposed as one candidate for secure transmissions in CPS, is not only more appropriate for these applications but also quite frugal in terms of prior requirements on shared keys. In this paper, we propose distortion-based metrics to protect CPS communication and show that it is possible to confuse adversaries with just a few bits of pre-shared keys. In particular, we will show that a linear dynamical system can communicate its state in a manner that prevents an eavesdropper from accurately learning the state.
