Public-Key Encryption with Registered Keyword Search

Public-key Encryption with Keyword Search (PEKS) enables a server to test whether a tag from a sender and a trapdoor from a receiver contain the same keyword. In this paper, we highlight some potential security concern, i.e. a curious server is able to answer whether any selected keyword is corresponding to a given trapdoor or not (called an offline keyword guessing attack). The existing semantic security definition for PEKS does not capture this vulnerability. We propose a new concept, namely Public-key Encryption with Registered Keyword Search (PERKS), which requires a sender to register a keyword with a receiver before the sender can generate a tag for this keyword. Clearly the keyword preregistration is a disadvantage. The payback is that the semantic security definition for PERKS proposed in this paper is immune to the offline keyword guessing attack. We also propose a construction of PERKS and prove its security. The construction supports testing multiple tags in batch mode, which can significantly reduce the computational complexity in some situations.
