我们构造公钥系统,支持加密数据的比较查询(x≥a)以及更一般的查询,如子集查询(x∈S)。此外,这些系统支持任意合取查询(P1),而不会泄漏单个合取的信息。我们提出了一个通用的框架,用于构建和分析公钥系统支持加密数据的查询。
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.
