Oblivious Message Retrieval

Authors: Zeyu Liu, Eran Tromer

Published in: CRYPTO 2022. Contributed Talk at RWC 2022.

Date:

This paper is about the Oblivious Message Retrieval for anonymous message delivery systems, such as private messaging services and privacy-preserving payment systems, need a mechanism for recipients to retrieve the messages addressed to them, without leaking metadata or letting their messages be linked.

XSPIR: Efficient Symmetrically Private Information Retrieval from Ring-LWE

Authors: Chengyu Lin, Zeyu Liu, Tal Malkin

Published in: ESORICS 2022.

Date:

Private Information Retrieval (PIR) allows a client to retrieve one entry from a database held by a server, while hiding from the server which entry has been retrieved. Symmetrically Private Information Retrieval (SPIR) additionally protects the privacy of the data, requiring that the client obtains only its desired entry, and no information on other data entries..

OpenFHE: Open-Source Fully Homomorphic Encryption Library

Authors: Ahmad Al Badawi, Jack Bates, Flavio Bergamaschi, David Bruce Cousins, Saroja Erabelli, Nicholas Genise, Shai Halevi, Hamish Hunt, Andrey Kim, Yongwoo Lee, Zeyu Liu, Daniele Micciancio, Ian Quah, Yuriy Polyakov, Saraswathy R.V., Kurt Rohloff, Jonathan Saylor, Dmitriy Suponitsky, Matthew Triplett, Vinod Vaikuntanathan, and Vincent Zucca

Published in: WAHC 2022.

Date:

Fully Homomorphic Encryption (FHE) is a powerful cryptographic primitive that enables performing computations over encrypted data without having access to the secret key. We introduce OpenFHE, a new open-source FHE software library that incorporates selected design ideas from prior FHE projects, such as PALISADE, HElib, and HEAAN, and includes several new design concepts and ideas.
