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∧ ⋯ ∧Pℓ) without leaking information on individual conjuncts. We present a general framework for constructing and analyzing public-key systems supporting queries on encrypted data.
