OBSCURE: Information-Theoretic Oblivious and Verifiable Aggregation Queries

Summary: OBSCURE delivers communication-efficient, information-theoretically secure MPC for oblivious aggregation over secret-shared data, hiding queries, results, and databases from clouds and networks. Optional privacy-preserving verification detects malicious behavior, with experiments demonstrating scalability to large datasets. (summarized by gpt-5.6-luna on Jul 24 2026)
