TWC TTP: Small: Collaborative: Privacy-Preserving Data Collection and Access for IEEE 802.11s-Based Smart Grid Applications

现代化的智能电网(SG)有望实现几种新的应用，如动态定价、需求响应和欺诈检测；然而，收集此类细粒度数据会带来隐私问题。该项目旨在设计和实施几种新的机制，用于在SG高级计量基础设施应用程序中保护数据收集和通信的安全，同时在访问数据时保护用户隐私。底层通信基础设施，即邻域网络，将利用使用IEEE802.11s的无线Mesh网络来构建，IEEE802.11s是针对Mesh联网的IEEE 802.11修正案。该项目研究了在邻域网络的数据收集过程中使用部分和完全同态加密的用户隐私保护机制。针对数据仓库中采集到的数据，研究了基于属性的访问控制机制。作为这些访问控制机制的一部分，研究了新的可扩展的密钥建立和组密钥管理方案。由IEEE 802.11 LINUX路由器组成的试验台是在服务质量约束下评估隐私机制开销的项目的一部分。试验床将成为研究人员、教育工作者和学生以及对SG通信和隐私感兴趣的公用事业公司的社区资源。确保实用的用户隐私解决方案将增加客户在SG应用中的参与度，节省成本和能源。该试验台将对从事SG通信工作的公用事业公司、研究人员和教育工作者有很大帮助。软件和技术手册将以开放源码文件的形式提供。有关智能电网的新研究生课程将被引入学术课程。

The modernized Smart Grid (SG) is expected to enable several new applications such as dynamic pricing, demand response and fraud detection; however, collection of such fine-grained data raises privacy issues. This project aims to design and implement several novel mechanisms for securing data collection and communication in SG Advanced Metering Infrastructure applications while preserving user privacy when the data are to be accessed. The underlying communication infrastructure, namely Neighborhood Area Networks, is to be built with wireless mesh networks using the IEEE 802.11s, an IEEE 802.11 amendment for mesh networking. The project investigates user privacy preservation mechanisms using partially and fully homomorphic encryption during data collection in the Neighborhood Area Networks. For the collected data at the data repository, attribute-based access control mechanisms are studied. As part of these access control mechanisms, novel scalable key establishment and group key management schemes are investigated. A testbed consisting of IEEE 802.11 Linux routers is part of the project to assess the overhead of privacy mechanisms under quality of service constraints. The testbed will be a community resource for researchers, educators and students as well as utility companies interested in SG communications and privacy. Ensuring practical user privacy solutions will increase the participation of customers in SG applications saving cost and energy. The testbed will be a great help to utilities, researchers and educators who work on SG communications. The software and technical manuals will be made available as open-source documents. New graduate courses on the Smart Grid will be introduced into the academic curriculum.
