2008 Third International Conference on Availability, Reliability and Security
New Efficient and Authenticated Key Agreement Protocol in Dynamic Peer Group
March 04-March 07
ISBN: 978-0-7695-3102-1
The members in the Dynamic Peer Group (DPG) are divided into several clusters according to Linker Cluster Architecture [1]. In each cluster, the members perform the BD protocol [2] to establish the cluster key and the TGDH protocol [3] is performed among the clusters to generate the group key. This method cannot only avoid the weakness of AKA(Auxiliary Key Agreement) of BD, but also reduce the computation cost of TGDH scheme. In our scheme the members have been authenticated based identity, and we prove the security in Random Oracle Model.
Index Terms:
Dynamic Peer Group, Key Agreement, ID-Based Signature, Provable Security, Random Oracle Model.
