CPS: Synergy: Collaborative Research: Towards Secure Networked Cyber-Physical Systems: A Theoretic Framework with Bounded Rationality

保护电网或运输系统等关键网络物理系统(NCP)的安全已成为国家和全球的主要优先事项。这类系统的网络性使它们容易受到网络和物理领域的一系列攻击，最近的威胁，如Stuxnet蠕虫，证实了这一点。为这类NCP开发安全机制与传统的联网系统有很大的不同，因为网络和物理子系统之间的相互依赖(攻击来自任何一个子系统)，攻击者或防御者之间可能的合作，以及环路中存在人类决策者。这项研究的主要目标是开发必要的科学和工程工具来设计适用于广泛应用领域的NCPS安全解决方案。该项目将开发一个多学科框架，将网络安全、控制理论、网络和犯罪学的原理编织在一起。该框架将包括建立在坚实的控制论和相关概念基础上的NCP的新型安全机制，允许将有限人类理性纳入NCPS安全的分析工具，以及与真实世界攻击场景的实验。一个新建立的跨机构NCPS模拟器将用于在现实环境中评估所提出的机制。这项研究超越了特定的网络物理系统领域，并为建立安全可靠的NCP提供了必要的工具。更广泛的影响包括NCPS研究和教育的新基础设施、学生培训、新课程以及侧重于代表性不足的学生群体的外联活动。

Securing critical networked cyber-physical systems (NCPSs) such as the power grid or transportation systems has emerged as a major national and global priority. The networked nature of such systems renders them vulnerable to a range of attacks both in cyber and physical domains as corroborated by recent threats such as the Stuxnet worm. Developing security mechanisms for such NCPSs significantly differs from traditional networked systems due to interdependence between cyber and physical subsystems (with attacks originating from either subsystem), possible cooperation between attackers or defenders, and the presence of human decision makers in the loop. The main goal of this research is to develop the necessary science and engineering tools for designing NCPS security solutions that are applicable to a broad range of application domains. This project will develop a multidisciplinary framework that weaves together principles from cybersecurity, control theory, networking and criminology. The framework will include novel security mechanisms for NCPSs founded on solid control-theoretic and related notions, analytical tools that allow incorporation of bounded human rationality in NCPS security, and experiments with real-world attack scenarios. A newly built cross-institutional NCPS simulator will be used to evaluate the proposed mechanisms in realistic environments. This research transcends specific cyber-physical systems domains and provides the necessary tools to building secure and trustworthy NCPSs. The broader impacts include a new infrastructure for NCPS research and education, training of students, new courses, and outreach events focused on under-represented student groups.
