| Abstract(in English) | In proxy re-encryption (PRE) schemes, the proxy re-encrypts a ciphertext C for Alice into which Bob can decrypt. Recently, Hana)ka et al. constructed the first strictly CCA-secure unidirectional PRE scheme (in the standard model). However, their scheme is inefficient because the transformed ciphertext is an encryption of many components. In this paper, we show a more efficient strictly CCA-secure unidirectional PRE scheme in the random oracle model, where the security is proved under the DBDHI assumption. |
