    Abstract

    We describe two Hierarchical Identity Based Encryption (HIBE) schemes which are selective-ID chosen ciphertext secure. Our constructions are based on the Boneh-Boyen and the Boneh-Boyen-Goh HIBE schemes respectively. We apply the signature-based method to their HIBE schemes. The proposed l-level HIBE schemes are directly derived from l-level HIBE schemes secure against chosen plaintext attacks without padding on identities with one-bit. This is more compact than the known generic transformation suggested by Canetti et al..
