Cache-Aided Private Information Retrieval with Partially Known Uncoded Prefetching: Fundamental Limits
Yi-Peng Wei, Karim Banawan, Sennur Ulukus
We consider the problem of private information retrieval (PIR) from non-colluding and replicated databases, when the user is equipped with a cache that holds an uncoded fractio…
The Capacity of Private Information Retrieval with Partially Known Private Side Information
Yi-Peng Wei, Karim Banawan, Sennur Ulukus
We consider the problem of private information retrieval (PIR) of a single message out of messages from replicated and non-colluding databases where a cache-enabled user (r…
Fundamental Limits of Cache-Aided Private Information Retrieval with Unknown and Uncoded Prefetching
Yi-Peng Wei, Karim Banawan, Sennur Ulukus
We consider the problem of private information retrieval (PIR) from non-colluding and replicated databases when the user is equipped with a cache that holds an uncoded fraction…
The Capacity of Private Information Retrieval from Byzantine and Colluding Databases
Karim Banawan, Sennur Ulukus
We consider the problem of single-round private information retrieval (PIR) from replicated databases. We consider the case when databases are outdated (unsynchronized), or…
Multi-Message Private Information Retrieval: Capacity Results and Near-Optimal Schemes
Karim Banawan, Sennur Ulukus
We consider the problem of multi-message private information retrieval (MPIR) from non-communicating replicated databases. In MPIR, the user is interested in retrieving mes…
