Abstract

We construct public-key systems that support comparison queries (x ≥ a) on encrypted data as well as more general queries such as subset queries (x ∈ S). Furthermore, these systems support arbitrary conjunctive queries (P1 ∧ ⋯ ∧ P) without leaking information on individual conjuncts. We present a general framework for constructing and analyzing public-key systems supporting queries on encrypted data.
