ID-based proxy re-encryption (IBPRE) allows a proxy with some information (a.k.a. re-encryption key) to transform the ciphertext under one identity to another ciphertext under another identity. These two ciphertexts can yield the same plaintext, while the proxy cannot get any information of the plaintext. Due to its transformable functionality, IBPRE can be used in many applications. Some of these applications require that the underlying IBPRE scheme is CCA-secure and anonymous. However, to the best of our knowledge, none of the existing schemes satisfy the security requirement. In this paper, we first extend the concept of IBPRE to that of anonymous IBPRE (AIBPRE), including the definition and security model. After that, we propose the first AIBPRE scheme, which can be proven-secure in the random oracle model based on the decisional bilinear Diffie-Hellman assumption and modified decisional bilinear Diffie-Hellman assumption.
