Federated learning (FL) is a machine learning setting where many clients (eg, mobile
devices or whole organizations) collaboratively train a model under the orchestration of a …

We present SimplePIR, the fastest single-server private information retrieval scheme known
to date. SimplePIR's security holds under the learning-with-errors assumption. To answer a …

We introduce the SPIRAL family of single-server private information retrieval (PIR) protocols.
SPIRAL relies on a composition of two lattice-based homomorphic encryption schemes: the …

Abstract 5 G is the fifth generation of cellular networks. It enables billions of connected
devices to gather and share information in real time; a key facilitator in Industrial Internet of …

This paper presents OnionPIR and stateful OnionPIR, two single-server PIR schemes that
significantly improve the response size and computation cost over state-of-the-art schemes …

We construct new private-information-retrieval protocols in the single-server setting. Our
schemes allow a client to privately fetch a sequence of database records from a server …

Contact tracing is an essential tool in containing infectious diseases such as COVID-19.
Many countries and research groups have launched or announced mobile apps to facilitate …

Tiptoe is a private web search engine that allows clients to search over hundreds of millions
of documents, while revealing no information about their search query to the search engine's …

This paper introduces protocols for authenticated private information retrieval. These
schemes enable a client to fetch a record from a remote database server such that (a) the …

This paper presents Checklist, a system for private blocklist lookups. In Checklist, a client
can determine whether a particular string appears on a server-held blocklist of strings …
