Key Agreement in Dynamic Peer Groups
ÐAs a result of the increased popularity of group-oriented applications and protocols, group communication occurs in many different settings: from network multicasting to application layer teleand videoconferencing. Regardless of the application environment, security services are necessary to provide communication privacy and integrity. This paper considers the problem of key agreement in dynam...
متن کاملConstant Round Dynamic Group Key Agreement
We present a fully symmetric constant round authenticated group key agreement protocol in dynamic scenario. Our proposed scheme achieves forward secrecy and is provably secure under DDH assumption in the security model of Bresson et al. providing, we feel, better security guarantee than previously published results. The protocol is efficient in terms of both communication and computation power.
متن کاملDistributed Collaborative Key Agreement Protocols for Dynamic Peer Groups
We consider several distributed collaborative key agreement protocols for dynamic peer groups. This problem has several important characteristics which make it different from traditional secure group communication. They are (1) distributed nature in which there is no centralized key server, (2) collaborative nature in which the group key is contributory; i.e., each group member will collaborati...
متن کاملDistributed Collaborative Key Agreement Protocol for Dynamic Peer Groups
In recent years, group-oriented applications and collaborative protocols are gaining popularity. This calls for group key management which forms the basic building block in achieving secure group communication. The points that differentiate it from the traditional communication are that they do not have a centralized server but a distributed system, group key being contributory and dynamic natu...
متن کاملDynamic Group Key Agreement in Tree-Based Setting
We present a provably secure tree based authenticated group key agreement protocol in dynamic scenario. Bilinear pairing and multi-signature are at the heart of our protocol. We prove that our protocol is provably secure in the standard security model of Bresson et al. An appropriate modification of Katz-Yung approach to tree based setting is adopted while proving its security against active ad...
