Tree-based group key agreement [PDF]
ACM Transactions on Information and System Security, 2004 Secure and reliable group communication is an active area of research. Its popularity is fueled by the growing importance of group-oriented and collaborative applications. The central research challenge is secure and efficient group key management. While centralized methods are often appropriate for key distribution in large multicast-style groups ...

Reinforcement learning based group key agreement scheme with reduced latency for VANET
网络与信息安全学报, 2020 Key agreement scheme of vehicle ad hoc networks (VANET) determines the privacy and security against user identity-based attacks,such as spoofing attack.The existing work updates the group shared key at a fixed frequency,which increases the processing ...

Key agreement based on automaton groups [PDF]
Groups Complexity Cryptology, 2019 Abstract We suggest several automaton groups as platforms for Anshel–Anshel–Goldfeld key agreement metascheme. They include Grigorchuk and universal Grigorchuk groups, Hanoi 3-towers group, the Basilica group and a subgroup of the affine group

Asymmetric Group Key Agreement [PDF]
, 2009 A group key agreement (GKA) protocol allows a set of users to establish a common secret via open networks. Observing that a major goal of GKAs for most applications is to establish a confidential channel among group members, we revisit the group key agreement definition and distinguish the conventional (symmetric ) group key agreement from asymmetric ...

An Improved ID-Based Group Key Agreement Protocol
Tsinghua Science and Technology, 2014 ID-based constant-round group key agreement protocols are efficient in both computation and communication, but previous protocols did not provide valid message authentication. An improvement based on attack analysis is proposed in this paper.

Attacking a Protocol for Group Key Agreement by Refuting Incorrect Inductive Conjectures [PDF]
, 2004 Automated tools for finding attacks on flawed security protocols often struggle to deal with protocols for group key agreement. Systems designed for fixed 2 or 3 party protocols may not be able to model a group protocol, or its intended security ...
