CPS: Small: Collaborative Research: Establishing Integrity in Dynamic Networks of Cyber Physical Devices

CPS：小型：合作研究：在网络物理设备的动态网络中建立完整性本研究的目标是为网络物理设备的动态网络开发节能的完整性建立技术。在这样的动态网络中，设备偶然地连接起来，并代表其他设备执行通用计算。然而，有些设备可能是恶意的，并影响计算的完整性。方法是为动态网络开发新的信任建立机制。现有的可信计算机制由于资源密集，并且需要设备具有专用硬件，因此不能直接适用于网络物理设备。这个项目从三个方面着手解决这些问题。首先对现有信任建立协议中的资源瓶颈进行了全面研究。其次，本研究的见解被用于为配备可信硬件的网络物理设备开发资源感知认证协议。第三，该项目正在为可能缺乏可信硬件的网络物理设备开发新的信任建立协议。该项目的一个关键成果是改进了对动态网络中平衡安全性和资源意识所需要的权衡的理解。动态网络允许网络物理设备形成一个高度分布式的、类似云的基础设施，用于涉及物理世界的计算。本项目开发的信任建立机制鼓励设备参与动态网络，从而释放动态网络的全部潜力。该项目包括开发动态网络应用程序，如分布式游戏和社交网络、本科课程和课程项目，从而促进这一关键人群的参与。

CPS:Small:Collaborative Research: Establishing Integrity in Dynamic Networks of Cyber Physical DevicesThe objective of this research is to develop energy-efficient integrityestablishment techniques for dynamic networks of cyber physical devices. In such dynamic networks, devices connect opportunistically and performgeneral-purpose computations on behalf of other devices. However, some devices may be malicious in intent and affect the integrity of computation. The approach is to develop new trust establishment mechanisms for dynamic networks. Existing trusted computing mechanisms are not directly applicable to cyber physical devices because they are resource-intensive and require devices to have special-purpose hardware.This project is addressing these problems along three research prongs. The first is a comprehensive study of the resource bottlenecks in current trust establishment protocols. Second, the insights from this study are being used to develop resource-aware attestation protocols for cyber physical devices that are equipped with trusted hardware. Third, theproject is developing new trust establishment protocols for cyber physicaldevices that may lack trusted hardware. A key outcome of the project is an improved understanding of the tradeoffs needed to balance the concerns of security and resource-awareness in dynamic networks.Dynamic networks allow cyber physical devices to form a highly-distributed,cloud-like infrastructure for computations involving the physical world. Thetrust-establishment mechanisms developed in this project encourage devices toparticipate in dynamic networks, thereby unleashing the full potential ofdynamic networks. This project includes development of dynamic networkingapplications, such as distributed gaming and social networking, inundergraduate curricula and course projects, thereby fostering theparticipation of this key demographic.
