信息物理系统完整性的设计时量化

Design-Time Quantification of Integrity in Cyber-Physical-Systems

Eric Rothstein Morris, Carlos G. Murguia, Martín Ochoa

摘要:

在软件系统中,可以通过分析源代码中的信息流来量化泄露或损坏的信息量。在网络物理系统中,信息流不仅存在于数字层面,也存在于物理层面,并在这两个层面之间来回流动。在这项工作中,我们提供了一种方法来正式分析一个网络物理系统复合模型(结合物理和控制)使用信息流理论的方法。我们使用这种方法来量化系统的脆弱性水平,相对于具有不同能力的攻击者。我们通过一个配水案例研究来说明我们的方法。

英文摘要:

In a software system it is possible to quantify the amount of information that is leaked or corrupted by analysing the flows of information present in the source code. In a cyber-physical system, information flows are not only present at the digital level, but also at a physical level, and to and fro the two levels. In this work, we provide a methodology to formally analyse a Cyber-Physical System composite model (combining physics and control) using an information flow-theoretic approach. We use this approach to quantify the level of vulnerability of a system with respect to attackers with different capabilities. We illustrate our approach by means of a water distribution case study.
