HARD PROBLEM(S) ADDRESSED

The goal of this project is to develop principles and methods to model privacy needs, threats, and protection mechanisms in cloud-assisted IoT systems. The work aims to address the hard problems of resilient architectures, security metrics as well as scalability and composability.

PUBLIC ACCOMPLISHMENT HIGHLIGHTS

  • Continued developing privacy-preserving protocols to support machine learning tasks using IoT devices.
  • Designed a blockchain-based framework to support privacy-preserving federated learning tasks in IoT devices. We also developed a proof-of-concept implementation. This work will be presented in 2019 ACM CCS conference.
  • Continued defining privacy risks in IoT applications, especially the ones involving inter-device interactions.
