Abstract:

We propose a new identity-based authenticated group key agreement protocol that provides both perfect forward secrecy and key integrity, while offering low communication and computational complexity. We prove the security of our protocol under the decisional bilinear Diffie-Hellman assumption in the random oracle model. In addition, we propose efficient auxiliary key agreement protocols that maintain perfect forward secrecy, while allowing members to discard their ephemeral keys in the same session in which they were created.
