| English Abstract | Authenticated key exchange (AKE) protocol is one of the most widely used cryptographic primitives, and lots of protocols have been proposed either in the certificate-based (cert-based) setting or in the identity-based (id-based) setting. In practical applications, entities from different settings may have the requirement to communicate with each other. Though there are works concentrated on supporting either multiple certification authorities (CAs) or multiple key generation centers (KGCs), very few papers have focused on the interoperability between the two settings. Furthermore, existing approaches are still inadequate in supporting parameters from different algebraic groups introduced by multiple CAs and multiple KGCs. In this paper, we focus on AKE protocols integrating cert-based settings and id-based settings with varied groups, and propose an AKE protocol where one entity is cert-based and the other is id-based, and the parameters of both entities may come from different groups. An extended AKE security model of [6,22] is proposed to support multiple KGCs and CAs. The proposed protocol is proved to be secure in the extended security model. Finally, we extend the protocol to achieve forward secrecy and resistance to leakage of both ephemeral keys. © 2012 Springer-Verlag.; Authenticated key exchange (AKE) protocol is one of the most widely used cryptographic primitives, and lots of protocols have been proposed either in the certificate-based (cert-based) setting or in the identity-based (id-based) setting.
