An tanpa nama skim penyulitan berasaskan identiti (IBE tanpa nama) memerlukan musuh tidak dapat menentukan identiti penerima daripada teks sifir yang disulitkan oleh kunci awam yang sepadan. Ketidaknamaan telah diformalkan dalam karya sebelumnya [1],[13], dan ini boleh dipertimbangkan di bawah serangan teks biasa pilihan dan serangan teks sifir pilihan adaptif, menghasilkan dua tanggapan keselamatan, ID-II-CPA dan ID-II-CCA, di mana II menandakan "ketidakbolehbezaan identiti." Walau bagaimanapun, cara untuk mendapatkan IBE tanpa nama selamat ID-II-CCA dalam model oracle rawak masih menjadi masalah yang mencabar. Kami mula-mula mencadangkan tanggapan baharu kesedaran teks biasa dalam dua latar identiti, yang dipanggil PATI. Kedua, kami membuktikan bahawa skim IBE adalah ID-II-CCA selamat jika ia selamat PATI. Akhir sekali, kami mencadangkan penukaran generik pertama untuk IBE tanpa nama daripada ID-II-CPA kepada ID-II-CCA dalam model oracle rawak.

Abstract: 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 IBE from ID-II-CPA to ID-II-CCA in the random oracle model.
