An Identity-Based Key-Exchange Protocol

摘要

An identity-based key-exchange protocol using a bilinear map is proposed and it is proved SK-sceure( session key secure) in the AM (authenticated links adversarial model) provided the BDDH (bilinear Diftie-Hellmen) assumption is correct. Then we applythe signature-based authenticalor to our protocol and obtain an id entity-based key-exchange protocol that is SK-secure in the UM (unauthenticated links adversarial model) provided the BDDH assumption is correct.
