Abstract: | We present a new two-party identity-based key agreement that is more efficient than previously proposed schemes. It is inspired on a new identity-based key pair derivation algorithm first proposed by Sakai and Kasahara. We show how this key agreement can be used in either escrowed or escrowless mode. We also describe conditions under which users of different Key Generation Centres can agree on a shared secret key. We give an overview of existing two-party key agreement protocols, and compare our new scheme with existing ones in terms of computational cost and storage requirements. |
