Dalam makalah ini, kami membina skim penyulitan berasaskan atribut (ABE) selamat kebocoran yang pertama (LR-CCA2) -skim penyulitan berasaskan atribut (ABE). Kami juga membina skim penyulitan berasaskan identiti (IBE) selamat LR-CCA2-secure pertama yang cekap dengan kadar kebocoran optimum. Untuk mendapatkan hasil kami, kami membangunkan hujah pengetahuan sifar bukan interaktif kuasi suaian baharu (QA-NIZK) untuk ketekalan teks sifir bagi skim selamat LR-CPA. Skim ABE kami diperoleh dengan meningkatkan keselamatan LR-CPA beberapa skim sedia ada kepada keselamatan LR-CCA2 dengan menggunakan hujah QA-NIZK kami. Skim ini hampir sama cekapnya dengan skim LR-CPA-secure yang mendasari.

Abstract: In this paper, we construct the first efficient leakage-resilient CCA2 (LR-CCA2)-secure attribute-based encryption (ABE) schemes. We also construct the first efficient LR-CCA2-secure identity-based encryption (IBE) scheme with optimal leakage rate. To obtain our results, we develop a new quasi-adaptive non-interactive zero-knowledge (QA-NIZK) argument for the ciphertext consistency of the LR-CPA-secure schemes. Our ABE schemes are obtained by boosting the LR-CPA-security of some existing schemes to the LR-CCA2-security by using our QA-NIZK arguments. The schemes are almost as efficient as the underlying LR-CPA-secure schemes.

We also construct the first efficient LR-CCA2-secure identity-based encryption (IBE) scheme with optimal leakage rate.
