Private Information Retrieval in an Anonymous Peer-to-Peer Environment
Private Information Retrieval (PIR) protocols enable a client to access data from a server without revealing what data was accessed. The study of Computational Private Information Retrieval (CPIR) protocols, an area of PIR protocols focusing on computational security, has been a recently …

Efficient Private Information Retrieval
… can reveal significant and possibly sensitive information about her. Private Information Retrieval (PIR) algorithms can be leveraged for providing perfect privacy to users' queries, though at a restrictive computational cost. In this work, we consider today's highly distributed computing …

Distributional Private Information Retrieval
A private-information-retrieval (PIR) scheme lets a client fetch a record from a remote database without revealing which record it has fetched. Classic PIR schemes treat all database records the same but, in practice, some database records are much more popular (i.e., commonly fetched) than others. …

Private Information Retrieval with Access Control
Private Information Retrieval (PIR) allows a user to query for a record from a remote database without revealing the query to the database server. However, PIR does not provide access control guarantees, allowing any user access to any record. Moreover, the database server cannot check access …

OnionChopper: A Modular Arithmetic Hardware Accelerator for Private Information Retrieval
Private information retrieval (PIR) is a protocol which allows a user to retrieve data from a database on a server without the server being able to deduce which records were retrieved. Due to the homomorphic cryptography systems required to make these protocols work and large amount of data …

Argos: Verifiable FHE Using Commodity Hardware
… used for real-world applications of FHE, such as private information retrieval (PIR) and private set intersection (PSI), where providing verifiability is imperative. By demonstrating how to combine cryptography with trusted hardware, Argos paves the way for widespread deployment of FHE-based …
