Summary Tripartite key agreement protocols enable three users to share a common and secure secret key by exchanging some information in a public channel. In this paper, we introduce the first attribute‐based tripartite key agreement protocol, which is a kind of identity‐based tripartite key agreement protocols, which the identities consist of descriptive attributes. Also, we propose an extended security model for these protocols and prove the security of our protocol in the random oracle model.Copyright © 2014 John Wiley & Sons, Ltd.
