Title:
Efficient Identity-Based Encryption Without Random Oracles
Authors: Brent R. Waters
Abstract:We present the first efficient Identity-Based Encryption
(IBE) scheme that is fully secure without random
oracles. We first present our IBE construction and reduce the
security of our scheme to the decisional Bilinear Diffie-Hellman
(BDH) problem. Additionally, we show that our techniques can be used
to build a new signature scheme that is secure under the
computational Diffie-Hellman assumption without random oracles.
