Abstract:
The private information retrieval (PIR) problem was first proposed by Chor et al. in 1995, and it is a canonical problem in the study of privacy issues that arise from the retrieval of information from public databases. Particularly, a PIR scheme is optimal if it simultaneously achieves the retrieval capacity and optimal sub-packetization. In this talk, we discuss building optimal PIR schemes over binary fields.
