| 摘 要： | An identity-based key-exchange protocol using a bilinear map is proposed and it is proved SK-secure(session key secure) in the AM (authenticated links adversarial model) provided the BDDH (bilinear Diffie-Hellmen) assumption is correct. Then we apply the signature-based authenticator to our protocol and obtain an identity-based key-exchange protocol that is SK-secure in the UM (unauthenticated links adversarial model) provided the BDDH assumption is correct.
