Efficient DPF-based Error-Detecting Information-Theoretic Private Information Retrieval Over Rings
The paper proposes a novel ring-based information-theoretic Private Information Retrieval (itED-PIR) scheme that overcomes the key size and communication overhead limitations of existing field-based APIR by utilizing prime-power-order Distributed Point Functions (DPFs).
Information-Theoretic Authenticated PIR: From PIR-RV To APIR
The paper proposes a novel, unconditionally secure information-theoretic Authenticated Private Information Retrieval (itAPIR) scheme that upgrades existing, less secure itPIR-RV schemes without overhead.
