Name of Granting or Contracting Agency/Entity: National Science Foundation

Program Title: N/A
CFDA Linked: Computer and Information Science and Engineering


Powerful and ubiquitous sensors and devices nowadays can collect data on all types of human activities and natural phenomena. These data sets are usually aggregated and stored in a distributed storage system, from which information can then be retrieved as needed for processing and computation. Making such systems private and secure is of paramount importance, which motivated the study of private information retrieval (PIR) systems. This project aims to develop a holistic view of PIR systems, and in the framework of this holistic view, to identify the information theoretic limits and develop efficient code constructions for the optimal tradeoffs between and among important system constraints, including communication, storage, complexity, and security.
