Multi-Party Authenticated Key Agreement Protocols from Multilinear Forms

Ho-Kyu Lee and Hyang-Sook Lee and Young-Ran Lee

Abstract: A. Joux presented a one round protocol for tripartitie key agreement and Al-Riyami developed a number of tripartitie, one round, authenticated protocols related to MTI and MQV protocols. Recently, Boneh and Silverleg studied multilinear forms, which provides a one round multi-party key agreement protocol. In this paper, we propose $(n+1)$ types of one round authenticated multi-party key agreement protocols from multilinear forms based on the application of MTI and MQV protocols.
