Identity-Based and Inter-Domain Password Authenticated Key Exchange for Lightweight Clients
We propose a four-party password authenticated interdomain key exchange protocol which makes use of properties of identity-based cryptography and secret public keys. Being passwor...

Identity-Based Traitor Tracing
We present the first identity-based traitor tracing scheme. The scheme is shown to be secure in the standard model, assuming the bilinear decision Diffie-Hellman (DBDH) is hard in...

Hierarchical Identity Based Encryption with Polynomially Many Levels
We present the first hierarchical identity based encryption (HIBE) system that has full security for more than a constant number of levels. In all prior HIBE systems in the literat...
