Under the emergence of the Internet of Things (IoT), tremendous amounts of data have been generated in a distributed manner from IoT devices, e.g., smart sensors, smartphones, cameras, etc. To effectively learn the patterns among such distributed data, distributed learning/federated learning frameworks have been explored to effectively utilize the distributed/decentralized data resource. However, the current distributed learning systems over IoT face inevitable challenges, mainly categorized into security, privacy, compatibility, and efficiency. For instance, first, the success of most existing learning systems relies heavily on a central server to coordinate the learning process. Second, traditional distributed learning requires the data on different devices to be in the same type/dimension. Third, the learning efficiency of the existing frameworks is another major concern. This work aims to systematically design a secure and fully decentralized learning method over IoT devices that enables the system to learn patterns from heterogenous data, i.e., data in different types/dimensions. This work will also deploy the developed method on a decentralized platform, i.e., blockchain, and design corresponding system protocols to eliminate the need to use a central server as in traditional distributed learning. On the other hand, the proposed system aims to exploit potential system vulnerabilities, develop attack and defense mechanisms, and theoretically analyze the system's reliability. Moreover, this work lays the groundwork for system research in dense IoT applications supported by decentralized learning. It generates preliminary experimental data necessary to develop an independent and competitive research agenda. This work will extend the traditional distributed/federated learning into a more general and practical scenario under IoT, where various types of data and IoT devices exist in the system. This work will also enhance the reliability of learning performance when a certain portion of the data in the network is attacked/malicious. Additionally, this work is potentially transformative as it may help generate innovative and secure decentralized deep learning techniques for numerous applications, e.g., smart cities, smart homes, and mobile health, since the proposed system can effectively utilize heterogeneous resources. It could also have significant impacts on research in transforming the existing centralized or distributed smart applications into a fully decentralized manner with security and performance guarantees. To address the education and social aspects, this project aims to provide students with resources to pursue advanced degrees and careers in STEM. This work plans to engage students from underrepresented groups as a part of a continuous effort to broaden participation in computing and develop advanced graduate-level courses to introduce new trends and cybersecurity challenges in future decentralized artificial intelligence over IoT.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在物联网(IoT)的出现下，智能传感器、智能手机、摄像头等物联网设备以分布式的方式产生了海量的数据。为了有效地学习这些分布式数据中的模式，人们探索了分布式学习/联合学习框架来有效地利用分布式/分散式的数据资源。然而，当前物联网上的分布式学习系统面临着不可避免的挑战，主要分为安全、隐私、兼容性和效率四个方面。例如，首先，大多数现有学习系统的成功在很大程度上依赖于一个中央服务器来协调学习过程。第二，传统的分布式学习要求不同设备上的数据处于相同的类型/维度。第三，现有框架的学习效率是另一个主要问题。这项工作旨在系统地设计一种安全的、完全分散的物联网设备学习方法，使系统能够从异质数据中学习模式，即不同类型/维度的数据。这项工作还将把开发的方法部署在一个去中心化的平台上，即区块链，并设计相应的系统协议，以消除传统分布式学习中使用中央服务器的需要。另一方面，该系统旨在挖掘潜在的系统漏洞，开发攻击和防御机制，并从理论上分析系统的可靠性。此外，该工作还为分布式学习支持的密集物联网应用的系统研究奠定了基础。它产生制定独立和有竞争力的研究议程所需的初步实验数据。这项工作将把传统的分布式/联合学习扩展到物联网下更通用、更实用的场景，其中系统中存在各种类型的数据和物联网设备。这项工作还将增强网络中某一部分数据受到攻击/恶意时学习性能的可靠性。此外，这项工作具有潜在的变革性，因为它可以帮助为许多应用程序生成创新和安全的分散式深度学习技术，例如智能城市、智能家居和移动医疗，因为所提议的系统可以有效地利用不同的资源。它还可能对将现有的集中式或分布式智能应用程序转变为具有安全和性能保证的完全分散的方式的研究产生重大影响。为了解决教育和社会方面的问题，该项目旨在为学生提供在STEM攻读高级学位和职业的资源。这项工作计划吸引来自代表性不足群体的学生，作为不断努力的一部分，以扩大对计算的参与，并开发高级研究生级别课程，以介绍未来物联网上去中心化人工智能的新趋势和网络安全挑战。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
