Exploring robustness in group key agreement

Proceedings 21st International Conference on Distributed Computing Systems, 2002
Secure group communication is crucial for building distributed applications that work in dynamic environments and communicate over unsecured networks (e.g. the Internet). Key agreement is a critical part of providing security services for group communication systems.

Secure Group Key Agreement Protocols

2018
This chapter focusses on Secure Key Exchange protocols executed among a group of parties, called group key exchange (GKE) protocols. Authentication and Key Establishment are very important in any secure communication. Authentication is generally based on long-term keys which can be associated with identities. To associate identities with long-term keys,

Group key agreement efficient in communication

IEEE Transactions on Computers, 2004
In recent years, collaborative and group-oriented applications and protocols have gained popularity. These applications typically involve communication over open networks; security thus is naturally an important requirement. Group key management is one of the basic building blocks in securing group communication.

Secure group key agreement

2004
Mit der Verbreitung offener Netze, insbesondere des Internets, fand auch die Gruppenkommunikation eine rasante Verbreitung. Eine Vielzahl heutiger Protokolle sind gruppen-orientiert: angefangen bei Multicast-Diensten in der Netzwerkschicht bis hin zu Videokonferenzsystemen auf der Anwendungsschicht. Alle diese Dienste haben Sicherheitsanforderungen wie

Authenticated Group Key Agreement for Multicast

2006
Secure 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 ...

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
