Anonymity from Asymmetry: New Constructions for Anonymous HIBE

Download www.eleves.ens.fr

A Hierarchical Identity Based Encryption (HIBE) system is anonymous if the ciphertext reveals no information about the recipient’s identity. create it. While there are multiple constructions for secure HIBE, far fewer constructions exist for anonymous HIBE. In this paper we show how to use asymmetric pairings to convert a large family of IBE and HIBE constructions into anonymous IBE and HIBE systems. We also obtain a delegatable-HVE which is a generalization of anonymous HIBE.
