English Abstract: | In ACM CCS 2007, Canetti and Hohenberger left an interesting open problem of how to construct a chosen-ciphertext secure proxy re-encryption (PRE) scheme without bilinear maps. This is a rather interesting problem and has attracted great interest in recent years. In PKC 2010, Matsuda, Nishimaki and Tanaka introduced a novel primitive named re-applicable lossy trapdoor function, and then used it to construct a PRE scheme without bilinear maps. Their scheme is claimed to be chosen-ciphertext secure in the standard model. In this paper, we make a careful observation on their PRE scheme, and indicate that their scheme does not satisfy chosen-ciphertext security. The purpose of this paper is to clarify the fact that, it is still an open problem to come up with a chosen-ciphertext secure PRE scheme without bilinear maps in the standard model. © 2011 International Association for Cryptologic Research. |
