CAREER: Towards Trustworthy Participatory Sensing

参与式感知是一种革命性的模式，人们感知他们的环境，并使用预先存在的通信基础设施自愿分享这些信息。通过在没有专用基础设施的情况下实现大规模传感，它在包括城市规划和智能交通在内的各个领域具有巨大的潜力。实现这一潜力取决于鼓励可能互不信任的用户之间共享传感器数据。该项目的目标是设计和实施一个可信赖的参与式感知系统，包括以下算法：(i)认证发布的感知内容的完整性，以便用户可以信任它；（ii）感知内容保护，以便更多用户贡献数据；（iii）生产者和消费者之间的匿名内容共享。它探索了一种新的可信参与式感知方法，每个传感器都有一个可信的硬件平台，除了主处理器之外，还有一个防篡改的可信硬件元素，只执行由可信第三方签名的代码。这以一种新的方式重塑了完整性和隐私问题，允许简单，可扩展和通用的解决方案。这样的系统可以防止潜在的滥用，鼓励用户参与，从而实现参与式感知。预期的项目成果包括一个新的系统模型和算法，用于可信赖的参与式感知，在英特尔amt平台上的实现，以及在现实世界的智能交通应用中的系统演示。研究结果将通过开源软件、会议出版物和俄勒冈科学与工业博物馆的展览进行传播。该项目还包括多层次的教育活动，以促进在计算机领域代表性不足的群体。

Participatory sensing is a revolutionary paradigm wherepeople sense their environment, and voluntarily share thisinformation using pre-existing communication infrastructure. Ithas tremendous potential to advance knowledge in diverse fieldsincluding urban planning and intelligent transportation by enablinglarge-scale sensing without dedicated infrastructure. Achieving thispotential hinges on encouraging sensor data sharing between userswho may not trust each other. The objectives of this project are to design and implement a trustworthyparticipatory sensing system, encompassing algorithms for (i)certifying the integrity of published sensory content, so users cantrust it, (ii) sensory content protection, so more users contributedata, and (iii) anonymous content sharing between producers andconsumers. It explores a novel approach for trustworthyparticipatory sensing with a trusted hardware platform for eachsensor, which besides the main processor, has a tamper-proof trustedhardware element that only executes code signed by a trusted thirdparty. This recasts the integrity and privacy problems in a new way,allowing for simple, scalable and versatile solutions. Such a system cancurb potential abuse, encourage user participation and thereby enableparticipatory sensing.Expected project results include a new system model and algorithms fortrustworthy participatory sensing, an implementation on the Intel AMTplatform, and system demonstration in a real-world intelligenttransportation application. The results will be disseminated viaopen-source software, conference publications and exhibits at the OregonMuseum of Science and Industry. The project also consists ofmulti-level educational activities to promote under-represented groupsin computing.
