Abstract

Nalla and Reddy [6] presented new ID-based tripartite authenticated key agreement protocols from parings. Recently, Boneh and Silverberg [4] studied a one round multi-party key agreement protocols using the certificates from multilinear forms. In this paper, we propose new ID-based multi-party authenticated key agreement protocols, which use the identity information of a user as his long-term public/private key, from multilinear forms. Also, these protocols are extended to provide key confirmation.
