Asymmetric Group Key Agreement with Traitor Traceability

2010 International Conference on Computational Intelligence and Security, 2010
Recently, the notion of asymmetric group key agreement (ASGKA) was introduced, in which the group members merely negotiate a common encryption key which is accessible to any entity, but they hold respective secret decryption keys. In this paper, we propose an ASGKA protocol with traitor traceability.

Group Key Agreement with Local Connectivity

IEEE Transactions on Dependable and Secure Computing, 2016
In this paper, we study a group key agreement problem where a user is only aware of his neighbors while the connectivity graph is arbitrary. In our problem, there is no centralized initialization for users. A group key agreement with these features is very suitable for social networks.

Research on authenticated key agreement in group settings

Proceedings of the 3rd international conference on Information security, 2004
An enhanced definition of implicit key authentication and a secure group key agreement scheme from pairings are presented. This scheme combines the merit of group public key and key trees to achieve a communication-efficient and authenticated group key agreement protocol. Besides, it avoids dependence on signature or MAC by involving member's long-term

Analysis of an efficient group key agreement protocol

IEEE Communications Letters, 2006
Recently, Jung (2006), proposed an efficient group key agreement protocol over authenticated channel. In this letter, we present a critique of the protocol.

A Framework for Robust Group Key Agreement

2006
Considering a protocol of Tseng, we show that a group key agreement protocol that resists attacks by malicious insiders in the authenticated broadcast model, loses this security when it is transfered into an unauthenticated point-to-point network with the protocol compiler introduced by Katz and Yung.

Group key agreement for wireless mesh networks

2009 IEEE 34th Conference on Local Computer Networks, 2009
Wireless mesh networks consist of stationary nodes that communicate over wireless connections. Since WLAN security standards are only applicable in the standard scenario where the access points are connected by a cable-bound backbone, nearly all mesh networks broacast messages in the clear.

An authenticated group key agreement for wireless networks

IEEE Wireless Communications and Networking Conference, 2005, 2005
One useful application of wireless networks is for secure group communication. The members in the group first run a group key agreement (GKA) protocol to establish a common group key that can be used to encrypt messages to be broadcast to the group. Authentication is necessary in GKA protocols to prevent adversaries from masquerading as group members ...

CLIQUES: a new approach to group key agreement

Proceedings. 18th International Conference on Distributed Computing Systems (Cat. No.98CB36183), 2002
The paper considers the problem of key agreement in a group setting with highly dynamic group member population. A protocol suite, called CLIQUES, is developed by extending the well known Diffie-Hellman key agreement method to support dynamic group operations. Constituent protocols are provably secure and efficient.

Authenticated group key agreement with admission control

Proceedings of the 3rd international conference on Information security, 2004
In this paper we present an authenticated group key agreement scheme with admission control for dynamic peer groups. Admission control is a necessary part of group communication. The scheme uses secret sharing to achieve integration of admission control and key agreement and addresses the pre-requisite for key management.
