An IBE Scheme to Exchange Authenticated Secret Keys.
Waldyr Benits, Routo Terada · 2004
We present a variant of the Boneh & Franklin Identiybased Encryption IBE scheme to derive an authenticated symmetric key-exchange protocol, when combined with a signature scheme. Our protocol uses 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.
