Abstract
-
A scheme, based on one-way functions, that works for a bounded number of queries, and where the server storage is linear in the number of queries plus the database size.
-
A family of schemes for an unbounded number of queries, whose security follows from a corresponding family of new hardness assumption that are related to the hardness of solving a system of noisy linear equations.
