英文摘要	An anonymous identity based encryption (anonymous ibe) scheme requires that an adversary can not determine the identity of the recipient from a ciphertext encrypted by the corresponding public key. the anonymity was formalized in previous works [1], [13], and this can be considered under chosen plaintext attack and adaptive chosen ciphertext attack, yielding two notions of security, id-ii-cpa and id-ii-cca, where ii denotes "indistinguishability of identities." however, how to obtain an id-ii-cca secure anonymous ibe in the random oracle model is still a challenging problem. we firstly propose a new notion of plaintext awareness in the two identities setting, called pati. secondly, we prove that the ibe scheme is id-ii-cca secure if it is pati secure. finally, we propose the first generic conversion for anonymous me from id-ii-cpa to id-ii-cca in the random oracle model.
