Abstract (in Japanese) (See Japanese page) 
(in English) Predicate encryption is an extension of public key encryption that enables much flexibility. There are many kinds of predicate encryption such as key policy attribute-based encryption, ciphertext policy attribute-based encryption, and doubly spatial encryption. In our work, we show that some of them are in fact equivalent in the sense that one implies another. By applying the conversion to previous predicate encryption schemes, we obtain many new predicate encryption schemes that provides various compactness trade-offs.
