Efficient Identity-Based and Authenticated Key Agreement Protocol
Authors: Yongge WangAbstract:
Several identity based and authenticated key agreement protocols have
been proposed in recent years and all of them have been shown to be
non-secure. It remains an open question to design secure identity
based and authenticated key agreement protocols.
In this paper, we propose an efficient identity-based and authenticated
key agreement protocol IDAK using Weil/Tate pairing. A security model
for identity based key agreement protocol is established and the security
properties of IDAK are proved in this model with random oracle. In particular,
it is shown that the IDAK protocol possesses all characteristics
that a secure key agreement should have.
