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

  • Extended the privacy-preserving classification protocol from the two-party model (i.e., client-server model) to a three-party model (i.e., client, server, and an assisting cloud).

We empirically tested the scalability of our three-party scheme to assess its effectiveness in IoT applications. We also extended the scheme from one-client case to multiple-client. The computation overload at each client in our scheme is independent of the number of classes but proportional to the number of features. The overall communication overhead is linear to the number of clients. These results are consistent with our asymptotic complexity analysis.
