CAREER: Privacy-Guaranteed Distributed Interactions in Critical Infrastructure Networks

关键基础设施系统（如智能电网）中的运营商（代理商）之间的信息共享是可靠和持续运营的基础。然而，为了系统稳定性和可靠性（效用）而共享数据与为了竞争优势（隐私）而保留数据之间的争论阻碍了此类系统中的数据共享，有时会带来灾难性的后果。这激发了一个数据共享框架，解决了竞争利益和代理的信息泄漏的关注，并使及时和受控的信息exchanges.This研究开发了一个基本的方法，在复杂的系统中，使用信息论和博弈论的分布式自利代理之间的隐私保证的信息共享。这个多学科的项目集中在智能电网的多代理网络抽象的四个相互关联的挑战：（1）与隐私约束的分布式交互的基本限制的表征;（2）信息理论的隐私措施的操作和实际意义;（3）形式化的隐私成本和信任的作用和重复的相互作用的合作;以及通过（4）用于智能电网中的隐私保证数据共享的分布式算法和协议来直接应用这些结果。该研究具有更广泛的意义，可以在具有严格隐私要求的各种复杂网络中实现信息共享，包括电子医疗保健和配水系统，并在电力系统中产生学术和行业合作。该研究项目结合了精心定制的外展工作，包括初中和高中学生的隐私意识，以及本科生和研究生，特别是女性，在研究中的积极参与。

Information sharing between operators (agents) in critical infrastructure systems such as the Smart Grid is fundamental to reliable and sustained operation. The contention, however, between sharing data for system stability and reliability (utility) and withholding data for competitive advantage (privacy) has stymied data sharing in such systems, sometimes with catastrophic consequences. This motivates a data sharing framework that addresses the competitive interests and information leakage concerns of agents and enables timely and controlled information exchange.This research develops a foundational approach to privacy-guaranteed information sharing among distributed self-interested agents in complex systems using information theory and game theory. This multidisciplinary project focuses on four mutually related challenges in multi-agent network abstractions of the Smart Grid: (1) characterization of the fundamental limits of distributed interaction with privacy constraints; (2) operational and practical significance of information-theoretic privacy measures; (3) formalizing the cost of privacy and the role of trust and repeated interactions for cooperation; and a direct application of these results via (4) distributed algorithms and protocols for privacy-guaranteed data sharing in the Smart Grid. The research has the broader implication of enabling information sharing in a variety of complex networks with strict privacy requirements including electronic healthcare and water distribution systems, and also engenders academic and industry collaborations in power systems. This research project incorporates carefully tailored outreach efforts including privacy awareness for middle- and high-school students, and active engagement of undergraduate and graduate students, especially females, in research.
