Secure key agreement for group communications

International Journal of Network Management, 2001
AbstractA 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 ...

Post-quantum Group Key Agreement Scheme

2020
Progress in quantum technologies forces the development of new cryptographic primitives that are resistant to attacks of an adversary with a quantum computer. A large number of key establishment schemes have been proposed for two participants, but the area of group post-quantum key establishment schemes has not been studied a lot.

A Group Key Agreement Scheme Revisited

2008 The Fourth International Conference on Information Assurance and Security, 2008
In PKC'2004, a constant-round group key exchange protocol is proposed. It takes advantage of the properties of the ElGamal encryption scheme combined with the standard secret sharing technique. In this paper, we show that the scheme can be greatly simplified because the standard secret sharing technique does not work well.

Password-based Dynamic Group Key Agreement

2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007), 2007
A password-based dynamic group key agreement protocol from tripartite Diffie-Hellman using pairing on elliptic curve is presented in this paper. In this scheme, due to all users share a common pre-distributed password, the setup of the key agreement is simplified and the performance is improved. In addition, each user establishes a relation between his

Golden Linear Group Key Agreement Protocol

2017
Security in group communication has been a significant field of research for decades. Because of the emerging technologies like cloud computing, mobile computing, ad-hoc networks, and wireless sensor networks, researchers are considering high group dynamics in communication security. Group key agreement protocol is for providing enough security for the

Certificateless Authenticated Group Key Agreement Protocol for Dynamic Groups

IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007
A group key agreement protocol is a process to establish a cryptographic key for a group of participants over an open network. In this paper, we propose a group key agreement (CAGKA) protocol, based on a certificateless public key cryptosystem. CAGKA protocol provides group key establishment and group membership change (join and leave) services for ...

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 Efficient Authenticated Group Key Agreement Protocol

2007 41st Annual IEEE International Carnahan Conference on Security Technology, 2007
Authenticated group key agreement is an important cryptographic mechanism underlying many collaborative and distributed applications. Some identity-based authenticated group key agreement schemes are proposed, however most of these protocols are vulnerable to insider attacks, while the other protocols are not efficient in communication. In this paper a
