| Abstract(in English) | Public Key Encryption with Keyword Search (PEKS)is a cryptographic primitive imparting the key- word search function without decoding for encrypted data. PEKS was proposed by Boneh et al. in 2004, and many studies have been made for it so far. To the best of authors' knowledge, the only one of the strong security defini- tion of PEKS was focused on, and weaker definitions have not been proposed. In general, cryptographic schemes with weak security can be constructed more simply, and it is useful to consider several security even for PEKS. In this paper, we revisit security definitions of PEKS. Specifically, we propose several security definitions of PEKS by combining several attacking models and security goals, which is the traditional approach to define security in the public-key encryption and signatures. We also investigate relations between the security definitions. |
