Two proposed identity-based three-party authenticated key agreement protocols from pairings

The use of pairings has been shown promising for many two-party and three-party identity-based authenticated key agreement protocols. In recent years, several identity-based authenticated key agreement protocols have been proposed and most of them broken. In this paper, we propose two three-party identity-based authenticated key agreement protocols applying bilinear pairings. We show that the proposed protocols are secure (i.e. conform to defined security attributes) while being efficient.
