Private retrieval, computing, and learning: Recent progress and future challenges

S Ulukus, S Avestimehr, M Gastpar… - IEEE Journal on …, 2022 - ieeexplore.ieee.org
Most of our lives are conducted in the cyberspace. The human notion of privacy translates
into a cyber notion of privacy on many functions that take place in the cyberspace. This …

Private information retrieval from coded databases with colluding servers

R Freij-Hollanti, OW Gnilke, C Hollanti… - SIAM Journal on Applied …, 2017 - SIAM
We present a general framework for private information retrieval (PIR) from arbitrary coded
databases that allows one to adjust the rate of the scheme to the suspected number of …

Private information retrieval from MDS coded data in distributed storage systems

R Tajeddine, OW Gnilke… - IEEE Transactions on …, 2018 - ieeexplore.ieee.org
The problem of providing privacy, in the private information retrieval (PIR) sense, to users
requesting data from a distributed storage system (DSS), is considered. The DSS is coded …

The capacity of symmetric private information retrieval

H Sun, SA Jafar - IEEE Transactions on Information Theory, 2018 - ieeexplore.ieee.org
Private information retrieval (PIR) is the problem of retrieving, as efficiently as possible, one
out of K messages from N non-communicating replicated databases (each holds all K …

The capacity of private information retrieval from Byzantine and colluding databases

K Banawan, S Ulukus - IEEE Transactions on Information …, 2018 - ieeexplore.ieee.org
We consider the problem of single-round private information retrieval (PIR) from N replicated
databases. We consider the case when B databases are outdated (unsynchronized), or …

The capacity of cache aided private information retrieval

R Tandon - 2017 55th Annual Allerton Conference on …, 2017 - ieeexplore.ieee.org
The problem of cache enabled private information retrieval (PIR) is considered in which a
user wishes to privately retrieve one out of K messages, each of size L bits from N distributed …

Capacity-achieving private information retrieval codes with optimal message size and upload cost

C Tian, H Sun, J Chen - IEEE Transactions on Information …, 2019 - ieeexplore.ieee.org
We propose a new capacity-achieving code for the private information retrieval (PIR)
problem, and show that it has the minimum message size (being one less than the number …

Fundamental limits of cache-aided private information retrieval with unknown and uncoded prefetching

YP Wei, K Banawan, S Ulukus - IEEE Transactions on …, 2018 - ieeexplore.ieee.org
We consider the problem of private information retrieval (PIR) from N non-colluding and
replicated databases when the user is equipped with a cache that holds an uncoded fraction …

The Capacity of T-Private Information Retrieval With Private Side Information

Z Chen, Z Wang, SA Jafar - IEEE Transactions on Information …, 2020 - ieeexplore.ieee.org
We consider the problem of T-Private Information Retrieval with private side information
(TPIR-PSI). In this problem, N replicated databases store K independent messages, and a …

Cross subspace alignment codes for coded distributed batch computation

Z Jia, SA Jafar - IEEE Transactions on Information Theory, 2021 - ieeexplore.ieee.org
The goal of coded distributed computation is to efficiently distribute a computation task, such
as matrix multiplication, N-linear computation, or multivariate polynomial evaluation, across …
