Paper 2024/482 , Yale University , Yale University , Yale University , Yale University Abstract Private Information Retrieval (PIR) is a two player protocol where the client, given some query $x \in [N]$ interacts with the server, which holds a $N$-bit string $\textsf{DB}$ in order to privately retrieve $\textsf{DB}[x]$.
Paper 2024/303 , Yale University , Yale University Abstract Recently, many works have considered Private Information Retrieval (PIR) with client-preprocessing: In this model a client and a server jointly run a preprocessing phase, after which client queries can run in time sublinear in the size of the database. In addition, such approaches store no additional bits per client at the server, allowing us to scale PIR to a large number of clients.
Paper 2023/204 TreePIR: Sublinear-Time and Polylog-Bandwidth Private Information Retrieval from DDH , Yale University , Yale University Abstract In Private Information Retrieval (PIR), a client wishes to retrieve the value of an index $i$ from a public database of $N$ values without leaking information about the index $i$.
