M Allaix, S Song, L Holzbaur, T Pllaha… - IEEE Journal on …, 2022 - ieeexplore.ieee.org
In quantum private information retrieval (QPIR), a user retrieves a classical file from multiple
servers by downloading quantum systems without revealing the identity of the file. The QPIR …

Private and secure distributed matrix multiplication schemes for replicated or MDS-coded servers

J Li, C Hollanti - IEEE Transactions on Information Forensics …, 2022 - ieeexplore.ieee.org

Semantic private information retrieval

S Vithana, K Banawan, S Ulukus - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
We investigate the problem of semantic private information retrieval (semantic PIR). In
semantic PIR, a user retrieves a message out of independent messages stored in replicated …

Capacity of quantum private information retrieval with colluding servers

S Song, M Hayashi - IEEE Transactions on Information Theory, 2021 - ieeexplore.ieee.org
Quantum private information retrieval (QPIR) is a protocol in which a user retrieves one of
multiple files from n non-communicating servers by downloading quantum systems without …

Multi-server weakly-private information retrieval

HY Lin, S Kumar, E Rosnes, AG i Amat… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org

Unified approach to secret sharing and symmetric private information retrieval with colluding servers in quantum systems

M Hayashi, S Song - IEEE Transactions on Information Theory, 2023 - ieeexplore.ieee.org
This paper unifiedly addresses two kinds of key quantum secure tasks, ie, quantum versions
of secret sharing (SS) and symmetric private information retrieval (SPIR) by using multi …
