Hierarchical identity-based broadcast encryption scheme from LWE
Journal of Communications and Networks, 2014 A hierarchical identity-based broadcast encryption (H-IBBE) scheme is an identity-based broadcast encryption (IBBE) scheme in a hierarchical environment. In order to obtain secure H-IBBE schemes in the quantum era, we propose an H-IBBE scheme based on the learning with errors problem assumption.

Anonymous Hierarchical Identity-Based Encryption (Without Random Oracles) [PDF]
Annual International Cryptology Conference, 2006 We present an identity-based cryptosystem that features fully anonymous ciphertexts and hierarchical key delegation. We give a proof of security in the standard model, based on the mild Decision Linear complexity assumption in bilinear groups. The system is efficient and practical, with small ciphertexts of size linear in the depth of the hierarchy ...
