CPS: Breakthrough: Secure Interactions with Internet of Things

这项研究的目的是(1)深入了解物联网(IoT)部署中的安全交互挑战，(2)开发一个实用的框架，以减轻对IoT交互的安全和隐私威胁，以及(3)在中型IoT试验台和用户研究中验证所提出的框架。新兴的物联网计算范式通过实现用户、传感器和执行器之间的交互，承诺在几乎所有领域都有新颖的应用。这些交互可以采取设备到设备(例如，蓝牙低能量(BLE))或人到设备(例如，语音控制)的形式。通过利用这些交互界面中的漏洞，对手可以未经授权访问物联网，从而能够跟踪、分析并对用户造成伤害。面对成千上万不同的物联网制造商、开发商和设备，确保所有设备在生产时得到适当保护并在生产后保持最新，即使不是不可能，也是非常具有挑战性的。物联网用户和管理员必须将他们的信任放在一组设备上，最不安全的设备会打破安全链。通过将信任基础从不同的制造商和开发商转移到用户控制下的单一框架，部署物联网设备将更可行，更不容易受到影响。建议的框架将有助于促进国家健康、繁荣和福利，并确保国防安全。保护物联网界面作为案例研究将被整合到研究生水平的课程中，并用于培训(特别是代表不足的学生和女性)具有需要理论和实践平衡结合的跨学科主题的学生，从而开发国家需要的领域的人力资源。拟议的研究还将显著促进对保护物联网交互界面在实践中所面临挑战的理解，从而促进科学进步。该项目将确定在当前和未来物联网部署中确保交互的总体方向。它将在不能适当地内置和维护安全的情况下提供额外的保护层。

The objective of this research is to (1) gain insights into the challenges of securing interactions in Internet of Things (IoT)deployments, (2) develop a practical framework that mitigates security and privacy threats to IoT interactions, and (3) validate the proposed framework in a medium-scale IoT testbed and through user studies. The emerging IoT computing paradigm promises novel applications in almost all sectors by enabling interactions between users, sensors, and actuators. These interactions can take the form of device-to-device (e.g., Bluetooth Low Energy (BLE)) or human-to-device (e.g., voice control). By exploiting vulnerabilities in these interaction surfaces, an adversary can gain unauthorized access to the IoT, which enables tracking, profiling and posing harm to the user. With the thousands of diverse IoT manufacturers, developers, and devices, it is very challenging, if not impossible, to ensure all devices are properly securedat production and kept up-to-date after production. IoT users and administrators have to place their trust in a set of devices, with the least secure device breaking the security chain. By shifting the trust base from the various manufacturers and developers to a single framework under the user's control, deploying IoT devices will be more feasible and less vulnerable. The proposed framework will help advance the national health, prosperity and welfare, and also secure the national defense. Securing IoT interface surfaces as case studies will be integrated in graduate-level courses, and used to train (especially underrepresented and female) students with interdisciplinary topics that require a balanced mix of theory and practice, thus developing human resources in the nationally needed areas.The proposed research will also significantly advance the understanding of the challenges to secure IoT interaction surfaces in practice, thus promoting the progress of science. This project will establish a general direction to secure interactions in the current and future IoT deployments. It will offer an additional protection layer in the cases where security cannot be properly built-in and maintained.
