ID-based tripartite Authenticated Key Agreement Protocols from pairings

This paper proposes ID-based tripartite authenticated key agreement protocols. The authenticated three party key agreement protocols from pairings [15], and the ID-based two party authenticated key agreement protocol [13] are studied. These two protocols are taken as the basis for designing three new ID-based tripartite authenticated key agreement protocols. The security properties of all these protocols are studied listing out the possible attacks on them. Further, these protocols are extended to provide key confirmation.
