An IBE Scheme to Exchange Authenticated Secret Keys
Waldyr Dias Benits Junior Routo Terada
We present a variant of the Boneh \& Franklin Identiy-based Encryption {\sc ibe} scheme to derive an authenticated symmetric key-exchange protocol, when combined with a signature scheme. Our protocol uses {\sc ibe} as a secure channel to establish a symmetric key between two users and, after that, further communication can be done by symmetric cryptography, much faster than pairing-based cryptography.
