    Utilizing Postponed Ephemeral and Pseudo-Static Keys in Tripartite and Identity-Based Key Agreement Protocols
    (International Association for Cryptologic Research, 2009) Fujioka, Atsushi; Suzuki, Koutarou; Ustaoğlu, Berkant
    We propose an new one-round implicitly authenticated three-party protocol that extends Joux's protocol as well as a two-party identity-based protocol. Our protocols have a single communication round that consists of ephemeral (one-time) public keys along with certificates in the tripartite protocol, and identities in the identity-based setting. As such our protocols are communication efficient and furthermore do not require enhanced message format.
