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.
