Secure and Private Structured-Subset Retrieval: Fundamental Limits and Achievable Schemes
Maha Issa, Anoosheh Heidarzadeh
This work introduces the \emph{Secure and Private Structured-Subset Retrieval (SPSSR)} problem. In SPSSR, a user wishes to retrieve one subset from an arbitrary family of size-…
Private Structured-Subset Retrieval
Maha Issa, Anoosheh Heidarzadeh
We introduce the \emph{Private Structured-Subset Retrieval (PSSR)} problem, where a user retrieves messages from a database of messages replicated across non-colluding…
Private Contiguous-Block Retrieval
Maha Issa, Anoosheh Heidarzadeh
We introduce the \emph{Private Contiguous-Block Retrieval (PCBR)} problem, where a user retrieves a block of messages with contiguous indices from replicated messages store…
On the Subpacketization Level of the Banawan-Ulukus Multi-Message PIR Scheme
