ID-Based Group Password-Authenticated Key Exchange
Password-authenticated key exchange (PAKE) protocols are designed to be se-cure even when the secret key used for authentication is a human-memorable password. In thispaper, we consider PAKE protocols in the group scenario, in which a group of clients, each ofthem shares a password with an “honest but curious” server, intend to establish a common secretkey (i.e., a group key) wi...
متن کاملAttack on Two ID-based Authenticated Group Key Agreement Schemes
Authenticated group key agreement problem is important in many modern collaborative and distributed applications. Recently, there are two ID-based authenticated group key agreement schemes have been proposed, one is Choi et al.’s [2] scheme, the other is Du et al.’s [3] scheme. They are all constructed from bilinear pairings based on Burmester and Desmedt scheme [1]. In this paper, we propose a...
متن کاملA New Efficient Authenticated ID-Based Group Key Agreement Protocol
Group key agreement (GKA) protocols Play a main role in constructing secure multicast channels. These protocols are algorithms that describe how a group of parties communicating over a public network can gain a common secret key. ID-based authenticated group key agreement (AGKA) cryptosystems based on bilinear pairings are update researching subject because of the simplicity of their public key...

متن کاملA Secure ID-Based Authenticated Group Key Exchange Protocol Resistant to Insider Attacks
Recently, several identity (ID)-based authenticated group key exchange (IDAGKE) protocols from bilinear pairings were proposed. However, they all suffered from different types of insider (participants) colluding attacks. In this paper, we present a new IDAGKE protocol from bilinear pairings. In the random oracle model and under some security assumptions, we demonstrate that the proposed protoco...
