Hierarchical identity-based encryption (HIBE) is an important extension of identity-based encryption (IBE) that uses the identity of a user as the public-key of the user. In HIBE, the identity of a user is represented as a hierarchical structure and a user with a private key can delegate his private key to next-level users.
