Information system for managing the register of serialized items based on a cloud service for enterprise economic development [PDF]
E3S Web of Conferences, 2023 This article describes the development of an information system for managing the register of serialized items based on a cloud service. Cloud services provide the ability to access computer equipment, hardware resources, disk memory and databases via the

Blind Interference Alignment for Private Information Retrieval [PDF]
, 2016 Blind interference alignment (BIA) refers to interference alignment schemes that are designed only based on channel coherence pattern knowledge at the transmitters (the "blind" transmitters do not know the exact channel values).

Two-Level Private Information Retrieval [PDF]
2021 IEEE International Symposium on Information Theory (ISIT), 2021 In the conventional robust $T$-colluding private information retrieval (PIR) system, the user needs to retrieve one of the possible messages while keeping the identity of the requested message private from any $T$ colluding servers. Motivated by the possible heterogeneous privacy requirements for different messages, we consider the $(N, T_1:K_1, T_2 ...

Asymmetric Leaky Private Information Retrieval [PDF]
IEEE Transactions on Information Theory, 2021 Information-theoretic formulations of the private information retrieval (PIR) problem have been investigated under a variety of scenarios. Symmetric private information retrieval (SPIR) is a variant where a user is able to privately retrieve one out of $K$ messages from $N$ non-colluding replicated databases without learning anything about the ...

Private Stateful Information Retrieval [PDF]
Proceedings of the 2018 ACM SIGSAC Conference on Computer and Communications Security, 2018 Private information retrieval (PIR) is a fundamental tool for preserving query privacy when accessing outsourced data. All previous PIR constructions have significant costs preventing widespread use. In this work, we present private stateful information retrieval (PSIR), an extension of PIR, allowing clients to be stateful and maintain information ...

On the Bringer–Chabanne EPIR protocol for polynomial evaluation
Journal of Mathematical Cryptology, 2012 Extended private information retrieval (EPIR) was defined by Bringer, Chabanne, Pointcheval and Tang at CANS 2007 and generalized by Bringer and Chabanne at AFRICACRYPT 2009.

A Storage-Efficient and Robust Private Information Retrieval Scheme Allowing Few Servers [PDF]
, 2014 Since the concept of locally decodable codes was introduced by Katz and Trevisan in 2000, it is well-known that information the-oretically secure private information retrieval schemes can be built using locally decodable codes.

Outsourced private information retrieval [PDF]
Proceedings of the 12th ACM workshop on Workshop on privacy in the electronic society, 2013 We propose a scheme for outsourcing Private Information Retrieval (PIR) to untrusted servers while protecting the privacy of the database owner as well as that of the database clients. We observe that by layering PIR on top of an Oblivious RAM (ORAM) data layout, we provide the ability for the database owner to perform private writes, while database ...
