PEKSrand: Providing Predicate Privacy in Public-Key Encryption with Keyword Search [PDF]
Recently, Shen, Shi, and Waters introduced the notion of predicate privacy, and proposed a scheme that achieves predicate privacy in the symmetric-key settings. In this paper, we propose two schemes. In the first scheme, we extend PEKS to support predicate privacy based on the idea of randomization.
