The paper proposes $\sf PVODTE$, a novel two-server protocol for private and verifiable outsourcing of decision tree evaluation that eliminates server-to-server communication, making it suitable for WAN deployments.

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).

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.

The paper proposes a novel, perfectly secure Information-Theoretic Distributed Point Function (ITDPF) that converts point functions into shares using asymptotically shorter secret keys compared to existing methods.
