Key Exposure Resistant Group Key Agreement Protocol
2021With the development of the Internet and computer science, the demand for collaboration over the Internet is constantly increasing. The group key agreement (GKA) protocol has been a desirable candidate for this demand. However, the possibility that some parties in the GKA protocol may be tampered with by the adversary leads to the stronger requirement ...

Secure key agreement for group communications
International Journal of Network Management, 2001AbstractA secure key agreement protocol for group communications is proposed in this paper, which ensures the authenticity of group members and the privacy of group messages, and provides the properties of perfect forward and backward privacy. In a group session, the common key is collaboratively established by all participants, hence the overhead of ...

Authenticated Group Key Agreement for Multicast
2006Secure multicast communication provides an efficient way to deliver data to a large group of recipients. Scalability, efficiency and authenticity are the key challenges for secure multicast. In this paper, we propose a novel group key agreement scheme called logical identity hierarchy(LIH) for multicast to support secure communications for large and ...

Tuning a two-round group key agreement
International Journal of Information Security, 2014In 2007, Bohli et al. (Int J Inf Secur 6:243---254, 2007) proposed a two-round group key agreement protocol in the random oracle model, which in addition to semantic security offers strong entity authentication and a security guarantee against malicious insiders.

Continuous Group Key Agreement with Active Security
2020A continuous group key agreement (CGKA) protocol allows a long-lived group of parties to agree on a continuous stream of fresh secret key material. CGKA protocols allow parties to join and leave mid-session but may neither rely on special group managers, trusted third parties, nor on any assumptions about if, when, or for how long members are online ...

CLIQUES: a new approach to group key agreement
Proceedings. 18th International Conference on Distributed Computing Systems (Cat. No.98CB36183), 2002The 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.

Group Key Agreement with Local Connectivity
IEEE Transactions on Dependable and Secure Computing, 2016In 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.

Asymmetric Group Key Agreement with Traitor Traceability
2010 International Conference on Computational Intelligence and Security, 2010Recently, 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.

Research on authenticated key agreement in group settings
Proceedings of the 3rd international conference on Information security, 2004An 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
