"WebAn Identity Based Encryption (IBE) system [24,5] is a public key system where the public key can be an arbitrary string such as an email address. A central authority uses a master key to issue private keys to identities that request them. Hierarchical IBE (HIBE) [17,14] is a generalization of IBE that mirrors an or-ganizational hierarchy.
