New private information retrieval codes for imperfect privacy
ICT ExpressIn this paper, we introduce new codes for the private information retrieval (PIR). The conventional Tian-Sun-Chen (TSC) scheme achieves PIR capacity under the perfect privacy conditions with the minimum message length. Based on the TSC scheme, weakly PIR

Polylogarithmic two-round argument systems
Journal of Mathematical Cryptology, 2008 We present a two-round argument system for NP languages with polylogarithmic communication complexity. We introduce a novel property of private information retrieval (PIR) schemes, that we call database-awareness.

Breaking the MDS-PIR Capacity Barrier via Joint Storage Coding
Information, 2019 The capacity of private information retrieval (PIR) from databases coded using maximum distance separable (MDS) codes was previously characterized by Banawan and Ulukus, where it was assumed that the messages are encoded and stored separably in the ...

Multi-Message Private Information Retrieval with Private Side Information [PDF]
2018 IEEE Information Theory Workshop (ITW), 2018 We consider the problem of private information retrieval (PIR) where a single user with private side information aims to retrieve multiple files from a library stored (uncoded) at a number of servers. We assume the side information at the user includes a subset of files stored privately (i.e., the server does not know the indices of these files).

Private Information Retrieval Schemes for Coded Data with Arbitrary Collusion Patterns
, 2017 In Private Information Retrieval (PIR), one wants to download a file from a database without revealing to the database which file is being downloaded. Much attention has been paid to the case of the database being encoded across several servers, subsets ...
